SMART SCIENCE

Here we propose a Gsm based weather sensing and reporting project. The system senses temperature, as well as light and humidity and conveys this to the user wirelessly. All this data from sensors is conveyed to the microcontroller. The microcontroller now processes this data and passes is on to a gsm modem interfaced to it. The gsm modem now encodes this data as sms message and sends this message to programmed user. Thus this puts forward a wireless gsm based weather monitoring system where the person does not need to be near the equipment to constantly monitor weather reports. The data is automatically sent to the user via a sms.

The high demand of automobiles has also increased the traffic hazards and road accidents. Life of the people is under high risk. The delay in reaching of the ambulance to the accident location and the traffic congestion in between accident location and hospital increases the chances of death of the victim. To overcome this problem our automatic ambulance rescue system comes to the rescue. This proposed IOT based accident detection system helps to reduce the loss of life due to accidents and also reduces the time taken by the ambulance to reach the hospital. To detect the accident there is accelerometer sensor present in this rescue system and the GSM module included sends messages about the location (by GPS) to the respective guardian and rescue team.

Security and safety have always become a basic necessity for the urban population. With the rapid urbanization and development of big cities and towns, the graph of crimes is also on the rise. The basic anti theft security systems that use sensors on walls or motion detection sensors can be avoided by using IR blocking clothes or hiding behind objects or simply identifying and disabling them. To secure and guard our house in our absence, we propose the IOT based Anti-theft Flooring System. This system monitors the entire floor for movement. One single step anywhere on the floor is tracked and user is intimated over IOT. This system is secure flooring tile connected with IOT when we go out of house, the system is to be turned on, then whoever comes inside the house it passes the information over IOT. One or two tiles for demonstration purpose, Piezo sensor / pressure sensor camera, wifi modem. Whenever the thief enters in the house, and steps on the floor immediately it is sensed by the sensor which passes on the signal to controller. The controller in turn processes it to be valid signal and then moves the camera to the area where movement was detected and then transmits it over the Internet for the home owner to check the image. We here use IOT for the web based GUI of IOT system which sounds an alert and shows the image captured to user.

The Embedded technology has entered almost in all aspects of day-to-day life, and the healthcare field is no exception for that the requirement for fully-equipped hospitals and diagnostic centers growing day by day as people are becoming more unaware of their health problems. An ECG signal can trace various physiological and abnormal conditions of the heart. This heart monitoring system also helps to inform the person whether he/she has any heart diseases or not. This is done by checking the heart beat level. In this system controller is used to scan ECG signal and search for pattern in common range, if the pattern will be in normal range then it gives the report of being normal if it is found that it is not in normal range then the person is suffering from some kind of heart disease. The following result is sent as an alert message on IOT. We here use IOT to develop the IOT based signaling part over internet.

Flooding is usually brought on by an increased quantity of water in a water system, like a lake, river overflowing. On occasion a dam fractures, abruptly releasing a massive quantity of water. The outcome is that a number of the water travels into soil, and ‘flooding’ the region. Rivers are involving river banks, in a station. Aside from lack of products and house and office property, streets infrastructure flood water consists of bacteria and sewage flow of waste sites and chemical spillage which leads to a variety of diseases afterwards. Flood predictions need information like: The speed of change in river stage on a real-time basis, which may help indicate the seriousness and immediacy of this threat. Understanding of the form of storm generating the moisture, such as length, intensity and areal extent, which is valuable for discovering potential seriousness of the flood. In this system we make use of a controller with water sensors, rain sensors to predict flood and alert respective authorities and sound instant alarm in nearby villages to instantly transmit information about possible floods using IOT. The water sensors are used to measure water level of 3 different locations. Also 3 different rain sensors are used to measure rain level of those 3 areas. These sensors provide information over the IOT using controller. On detection of conditions of flooding the system predicts the amount of time it would take to flood in a particular area and alerts the villages/areas that could be affected by it. The system also calculates the time it would take for flood to reach them and provides a time to people so that they can evacuate accordingly. .

Coal mining is the process of extracting coal from the ground. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. Underground mining industry comes to the category, where each and every parameter such as methane gas, high temperature, fire accidents and so on has to be monitored regularly. Safe production level of coal mine is still low, disasters in coal mine occur frequently, which lead to great loss of possession and life. The disasters happening in coal mine are due to the complexity of mine environment and the variety of work carried out in coal mine, so it is very necessary to monitor the working environment of coal mine. To get over this problem, projects have proposed a wireless sensor network’s application in coal mining safety system. In this wireless sensor network’s application system there will, be master controllers and slave controllers. Slave controllers will detect the danger and give alert through RF to master controller and it will raise the alarm in all tunnels and also raise message on IOT, which will help to take action as soon as possible. This monitoring, alerting system and master controller is powered by microcontroller. Slave consists of temperature sensor, water sensor, methane and carbon dioxide sensor and RF transmitter which collect temperature, humidity and methane values underground of coal mine and also has a panic/emergency button.

Well it is a quite shocking fact but prison escapes are not very uncommon occurrences. There is no exact data count but we have all heard and still keep hearing of a variety of prison escapes happening globally. The fact that such number of inmates may still be roaming among us is itself scary. Well so here we propose a prisoner tracking system that helps detect prison breaks and instantly alert authorities using IOT. The system makes use of a microcontroller based circuit to achieve the task using RF technology. We make use of RF trackers on each inmate to detect their presence in the premises. The 2 central monitoring units are used to scan through all inmates as per data fed to it and constantly keep track of each prisoner. Each prisoner is mounted with a RF tracker transmitting a unique prisoner code wirelessly. Whenever a prisoner exits the facility the centralized system is unable to receive his/her code. At that time the receiver circuitry instructs the controller to tack action against particular prisoner. The System now transmits the prisoner details over to the officers alerting portal to send out instant alert and catch the prisoner. Here we use IOT to develop the online alerting portal system to receive input from monitoring device and display alert and sound alarm through internet.

The IOT industry protection system using Arduino is a system designed to protect industries from losses due to accidents using Internet of things. Gas leakages may lead to fires leading to huge industrial losses, also instant fire detection is needed in case of furnace blasts or other conditions. Also low lighting in industries may create improper work conditions increasing the probability of accidents. The system makes use of arduino to achieve this functionality. The system makes use of temperature sensing along with light and gas sensing to detect fire, gas leakage as well as low lighting to avoid any industrial accidents and prevent losses. The system consists of light, gas and temperature sensors interfaced with arduino and LCD screen. The sensor data is constantly scanned to record values and check for fire, gas leakage or low light and then this data is transmitted online. The wifi module is used to achieve internet functionality. The IOT server then displays this information online, to achieve the desired output.

Growth in population has led to growth in technology. People use car on large number and number of accidents taking place, is increasing day-by-day. Road accidents are undoubtedly the most frequent happening cases and overall, the cause of the most damage. There are many dangerous roads in the world like mountain roads, narrow curve roads, T roads. Some mountain roads are very narrow and they have many curves. The problems in these curve roads are that the drivers are not able to see the vehicle or obstacles coming from another end of the curve. If the vehicle is in great speed then it is difficult to control and there are chances of falling off a cliff. Hence there is a need of many road safety systems. To avoid these problems in curve roads of mountain areas, proposed this vehicle accident prevention system. This accident prevention system using sensors is powered by micro controller; it consists of IR sensors, LED lights, and buzzer. When two cars pass from the opposite side of a mountain curve the IR sensor senses the car and LED color changes to red and raises the buzzer giving signal of danger and then it changes one LED color into green to allow the one car to pass and then the other LED color turns green. In this way we can prevent the accidents of curved road.

Smart Medicine Pill Reminder Project main aim of developing this Kit is to remind medicines just like an alarm. In this Smart Medicine Pill Reminder Project, we are using Arduino board, Voice playback module connected to Amplifier and this connected to Speaker we have an LCD also to display that, the main intention before developing this project is to usually remind the medicines which have to be taken in the daily schedule and it is especially useful for old age people, patients, and busy people. .

Shopping is easy but waiting on a bill counter after shopping is too boring and tedious task. Huge amount of rush plus cashier preparing the bill with barcode scanner is too time consuming and results in long ques. So here we have made an innovative project which will be placed in the shopping trolley itself. The system consists of a RFID reader which is controlled by microcontroller. So whenever the shopper puts any product in trolley it is been detected by the RFID module and it is displayed on LCD along with the price of the product. As the shopper adds more things it is detected by the module and the price according to that increases. In case if customer changes his/her mind and doesn’t want any product added in the trolley he can remove it and the price added will be deducted automatically. At the end of shopping the shopper will press the button which when pressed ads the entire product along with their price and gives the total bill to be paid. At exit for verification the shopkeeper can verify the shopping with the help of master card. Hence this system is suitable for use in places such as supermarkets, where it can help in reducing man power and in creating a better shopping experience for its customers.

Wearable Technologies are devices which can be worn by the user & simultaneously process and display relevant information on the wearer. Wearables are considered as the biggest innovation in technology since the Smartphone – and the possibilities are endless. Through this project you will build an electronic device that can be worn and used to display the heart rate of any individual on the display mounted on the glove. If you are fascinated with the wearable gadgets and wants to know how the whole system operates, then this electrical project is just for you.

GSM based Patient Health Monitoring Project mainly works for allowing doctors or relatives of patient to check the status of patient health remotely. The system calculates the heartbeats and body temperature of patient and if it goes above certain limit then immediate informative alert message will be sent to the registered number. For this system we used Microcontroller which is interfaced with LCD display, heartbeat sensor, and temperature sensor. The system also featured with manual health button using that the patient with some other issues will also able to contact with doctor so, the system is very helpful for saving life of patient. The system also introduced a function through which a doctor will able to check the status of patient after a certain interval of time by sending message. The system efficiently updates doctor about health of patient as well as accurately calculates the health parameter of patient.

The IOT based paralysis patient health care system is a system designed to help the patient convey various messages to doctors, nurse, or his/her loved ones sitting at home or office over the internet. The system makes use of a microcontroller based circuitry to achieve this functionality. It makes use of a hand motion recognition circuit and a receiver plus transmitter circuit. The hand motion circuit is used to detect hand movements using accelerometer and then transmit this information wirelessly over RF to the receiver system. The receiver system is designed to receive and process these commands and display them over the LCD display as well as transmit the data online over to IOT server. The IOT server then displays this information online, to achieve the desired output.

As we know coma is a state of unconsciousness in which patient cannot feel or respond to the pain, light or sound, it does not initiate volunteering any actions. Patients in a coma state need to have a continuous update of Blood pressure, temperature, humidity, and urine level. Doing this manually can become almost impossible to keep updates of multiple patients at the same time. In order to address this situation, our system comes to the rescue; this system will collect the information of patients with the help of sensors. These sensors use WIFI to communicate this information to the internet. This system is powered by the controller it includes a blood pressure monitoring unit and an ultrasonic sensor to check urine, temperature sensor, motion sensor, and an LCD display. When we turn the system on, it gets connected to the website using WIFI; System monitor shows four signs namely heart rate, temperature, humidity, and urine output. While testing heart rate function of the system, the heart rate and blood pressure value get updated over IOT and LCD display. As we know the patient who is in comatose cannot urinate on their own so a rubber tube is inserted into their bladder to remove urine. This system tests urine level and also updates the value over IOT and LCD, when the patient urinates. In case if the patient regains consciousness and attempts to move, the sensor will detect the motion and update it over IOT and LCD. In this way, our system monitors the comatose patients.

These days we have an increased number of heart diseases including increased risk of heart attacks. Our proposed system users sensors that allow to detect heart rate of a person using heartbeat sensing even if the person is at home. The sensor is then interfaced to a microcontroller that allows checking heart rate readings and transmitting them over internet. The user may set the high as well as low levels of heart beat limit. After setting these limits, the system starts monitoring and as soon as patient heart beat goes above a certain limit, the system sends an alert to the controller which then transmits this over the internet and alerts the doctors as well as concerned users. Also the system alerts for lower heartbeats. Whenever the user logs on for monitoring, the system also displays the live heart rate of the patient. Thus concerned ones may monitor heart rate as well get an alert of heart attack to the patient immediately from anywhere and the person can be saved on time.

Surveillance plays a major role for intelligence gathering, prevention of crime, the protection of a process, person, group or object, or the investigation of crime. In case of farmlands or agricultural lands is very important to protect the area from animals. There are many techniques undertaken to prevent human intruders, but they fail to protect from the main enemies of farmers that are animals which destroy the crops. There is a huge need to keep away scarecrows and wild animals. To avoid such damages farm protector drone can be used. In this farm protection system, the Farm protector drone helps to protect the farm from this damage. It will surveillance the farm, a farmer can keep watch on their farms, by keeping an hour difference. They can fly this drone manually just by sitting at one place, they can see the entire farm view. If they find birds or animals destroying the farm, they can press the button on the remote which will further make sound and the animals will run. This drone will save the time of the farmer and also helps to protect their farm.

Waste Management and segregation is a much-needed process in metro cities and urban areas due to spreading of diseases. It is estimated that India produces around 42.0 million tons of municipal solid waste annually at present. Waste lying littered in the surrounding, dumped on open lands, becomes a major problem for various types of disease-causing bacteria and viruses hence, segregation, transport, handling and disposal of waste must be managed properly to minimize the risks of the public and environment. When mixed dry and wet waste breaks down in lowland, it creates nasty greenhouse gases. Segregation makes it attainable to utilize and recycle the waste effectively. This waste segregator system can easily segregate waste. When waste is thrown in the pipe, IR sensor will sense the waste. Waste is divided into three categories namely Wet, Dry and Metallic. Another sensor will sense the garbage category. As per the algorithm used, if the waste is metallic then the mechanism will bring the metal collecting bin below the pipe and with the help of servo motor the waste will fall into the metal bin. Similarly, the process will repeat if wet waste is sensed. If the sensor doesn’t activate both the sensor category then the waste will be considered to be a dry waste.

With increase in population we have an increase in the garbage around urban areas. Here we propose a smart dustbin that operates automatically to help solve this issue using IOT and sensor based circuitry. Usual dustbins require to be opened by pressing foot against its lever and then throwing garbage. Also a person needs to keep track when it is full so that it can be emptied and does not overflow. Here we propose a smart dustbin that does all this by itself. Our system consists of a sensor in order to detect human objection sensor and on a objection foot tap it opens automatically without anyone needing to press its lever. The dustbin opens automatically when it receives the signal and closes its hatch. Also the dustbin consists of a level sensing ultrasonic sensor that constantly measures the level of garbage in the bin and automatically detects if it is about to fill up. The dustbin now consists of a smart circuitry that transmits this information over the web to signal the main garbage collector of the facility to empty the particular garbage bin. We use IOT to develop the online web part for the IOT system. This bin is of a vast usage in offices, homes and even in public places for garbage management. Thus we get a fully automated smart dustbin that allows for automated garbage cleaning.

Today, world is facing major garbage crisis- the product of rapid economic growth, overcrowding, poor urban planning, corrosive corruption, and political dysfunction. This is mainly due to the rapid increase in population as well as physical resources. The present tried and tested strategies of trash collection have been proved ineffective. And the world nowadays is looking at smarter ways for overcoming the garbage assortment problem. This project presents the Garbage Collector robot for footpath using Arduino microcontroller. The robot is built on a metallic base, which is powered by a battery of 12V. The robot is designed to collect Garbage from a footpath, public places (parks, schools, and colleges), mostly cemented paths and beach. The robot cannot be used on muddy surfaces. The robot is built in such a way that, when it is powered ON, it will move on the path defined in the program. When it encounters any obstacle, depending on the conditions applied in the program the robot proceeds with further motion and then the robot picks up the garbage.

A green house is where plants such as flowers and vegetables are grown. Greenhouses warm-up during the day when sun-rays penetrates through it, which heats the plant, soil and structure. Green houses help to protect crops from many diseases, particularly those that are soil borne and splash onto plants in the rain. Greenhouse effect is a natural phenomenon and beneficial to human being. Numerous farmers fail to get good profits from the greenhouse crops for the reason that they can’t manage two essential factors, which determines plant growth as well as productivity. Green house temperature should not go below a certain degree; High humidity can result to crop transpiration, condensation of water vapor on various greenhouse surfaces, and water evaporation from the humid soil. To overcome such challenges, this greenhouse monitoring and control system comes to rescue. This project demonstrates the design and implementation of a various sensors for greenhouse environment monitoring and controlling. This greenhouse control system is powered by microcontroller it consists of temperature sensor, light sensor, soil moisture sensor, LDR sensor, LCD display module, DC fan, Bulb and pump. Temperature sensor senses the level of temperature. If it goes high DC fans gets on and when the temperature goes low the fan gets off. Soil moisture sensor, senses the water level as the level decreases the pumps gets on. In the absence of light, the LDR sensor senses and the bulb start glowing. By this way it will become easy to monitor and control the system.

Crops in farms are many times ravaged by local animals like buffaloes, cows, goats, birds etc. This leads to huge losses for the farmers. It is not possible for farmers to barricade entire fields or stay on field 24 hours and guard it. So here we propose automatic crop protection system from animals. This is a microcontroller based system uses a motion sensor to detect wild animals approaching near the field. In such a case the sensor signals the microcontroller to take action. The microcontroller now sounds an alarm to woo the animals away from the field as well as sends sms to the farmer so that he may know about the issue and come to the spot in case the animals don’t turn away by the alarm. This ensures complete safety of crops from animals thus protecting the farmer’s loss.

The objective of this project is to monitor the flood situation & send alert in case of danger in the form of text message. The main objective of this project is to detect rising water level in a river at a reasonable distance from the rail track/ roadways and intimate that to the respective authorities through SMS, to take appropriate action. Floods lead to a vast loss of life and property in many countries. But in developing countries the lack of proper technology leads to more loss of life and property due to flood. This is due to lack of flood detection systems. Our project solves problem by implementing an early flood detection mechanism. In this project we will connect electrodes at different levels. Electrodes will be interfaced with µC through comparator. GSM modem containing a SIM card will be connected to µC. At the other end mobile will be used. Mobile number of user will be stored in µC coding. Whenever water level reaches to electrodes. SMS will be sent to mobile.

Accidents are the most common cause of death for the peoples who drive vehicles. Accidents happen, even to the people who are careful, but many accidents may be avoidable if simple precautions are taken. One of the major reasons for the accident is drink and drive. We can avoid these accidents by providing the eye blink and alcohol sensors to the drivers. The eye blink switch responds to the voluntary blink of the eye and requires minimal calibration. It discriminates between voluntary and involuntary blinks. Existing System Most of the accidents occur due to lack of concentration and tiredness of the driver. The number of accidents increases due to lack of preventive measures. Proposed System, to overcome these problems we make use Eye-blink and Alcohol sensors to monitor the status of the driver. In one application when the driver is tired, the eye-blink sensor compares with the predetermined count in the microcontroller and if it is abnormal, the microcontroller generates an alarm signal and the alert message is displayed in the LCD. In the meanwhile, the motor gets stopped. In other application, if the driver is in a drunken state, the alcohol sensor detects the abnormality by comparing the predetermined values in the microcontroller and the alert message is displayed on the LCD. Meanwhile, the motor gets stopped ant driver is in a safe condition.

When an individual riding his/her bike, meets with an accident, there is a chance that the individual may suffer from a serious injury or expire instantaneously and there is no one around to help him. Well this system is a solution to the problem. The system acts as an accident identification system that gathers and sends this vehicle information that met with an accident, and conveys it to the nearest control room. For this the user vehicle is fixed with an RF transmitter circuit that has a vibration sensor along with microcontroller, RF encoder and also fitted with an RF transmitter. Each and every control room must have an RF receiver fitted to receive the transmission. Whenever a user vehicle meets with any accident, the vibration sensor detects and gives its output. This output is then detected by the microcontroller. Now the microcontroller sends this change detection signal to an RF transmitter. The RF transmitter now intern begins transmitting this accident data. The nearest RF receiver reads the signal and then shows it on an LCD screen. The person monitoring the LCD screen may react to it, reach the accident location and help the needful.

Car parking is a major problem in urban areas in both developed and developing countries. Following the rapid increase of car ownership, many cities are lacking car parking areas. This imbalance is partially due to ineffective land use planning and miscalculations of space requirements during first stage of planning. Shortage of parking space, high parking tariffs, and traffic congestion due to visitors in search for a parking place are only a few problems examples of everyday parking. Parallel parking is usually a driver’s worst nightmare because; it not only requires the driver’s skills but also increases the possibility of other drivers bumping into their parked vehicle. Autonomous car parking was introduced to encounter the above car parking problems, hence projects has developed an advanced automatic car parking system that enables a car to park it-self. This self-parking car project consists of Arduino board, obstacle sensor which detects the objects in front and back of the vehicle, ultra-sonic range finder to detect the parking distance, LCD module to display various information of the program, Motor driver to drive a DC gear motor and a servo Motor to control steering.

A large number of personnel are deployed to check for unauthorized parking and fine those owners. But owners evade the fine by various illegal means like bribing the personnel, threatening them etc. Towing vans need to manually search for illegally parked vehicles. This system requires large overhead costs in manpower payment, fuel and other physical surveillance. Here we propose a system that allows for automatic illegal parking detection and alerting. The system consists of integrating an RFID transmitter in every vehicle. RFID receiver circuit is mounted on every area where parking is not prohibited. If a vehicle is parked in an area where parking is not prohibited the RFID transmitter comes in rang of the receiver circuit. Once this happens the RFID reader reads the transmitter id and can instantly alert authority with area code so that authorities can directly arrive at the spot and sends a sms (GSM) to the car owner about the fine imposed on the vehicle.

The main purpose of this project is to prevent vehicle theft. This functionality is achieved by detecting vehicle status in theft mode and by sending an SMS which is generated automatically. This SMS is then sent to the owner of the vehicle. The owner can then send back the SMS tin order to disable the ignition of the vehicle. Thus in this way crimes can be reduced to a great extent as vehicles today are being stolen in large number. Hence, vehicles today require high security which can be achieved with the help of this application. How the system works is when a person tries to steal the vehicle, the microcontroller is interrupted and the command is sent to the GSM modem to send SMS. On the receipt of the message, the owner sends back the SMS to the GSM modem. This is done in order to stop the engine. This GSM modem is interfaced to the microcontroller. This microcontroller on the receipt of the message uses a mechanism that helps to stop the engine. Motor is being used in this project in order to indicate vehicle ON/OFF state. Further enhancement can be done to this project by using a GPS system that helps to find out the exact position of the vehicle with the help of its latitude and longitude which then can be sent to the owner of the vehicle via SMS. This data can be then entered by the owner on Google map to find out the exact location of the vehicle.

The proposed system is an anti bike theft system that makes bike theft almost impossible. This anti bike theft project is a system attached to the bike ignition system. In order to start the ignition system, user has to enter his strong password. Only when the right password is entered does the ignition system start. The bike user must carry an RF receiver device with him. Well the owner may now park his bike as intended and lock it. If a thief tries to break the key lock he still cannot start engine ignition without entering the right password. The system now prompts user to enter the password, if he enters the wrong password the system sends signals through RF sender circuit connected to it. These signals are then received by RF receiver device with the user and he is alerted. The system also engages the thief by prompting to enter the password again. Well if the user does not arrive within certain time limit to take actions and enter right password the system then sounds a buzzer to alert passersby or security personnel nearby. The alarm stops as soon as user enters the right password.

Women’s safety is a very important issue due to rising crimes against women these days. To help resolve this issue we propose a gps based women’s safety system that has dual security feature. This device consists of a system that ensures dual alerts in case a woman is harassed or she thinks she is in trouble. This system can be turned on by a woman in case she even thinks she would be in trouble. It is useful because once an incident occurs with a woman she may or may not get the chance to press the emergency button. In a button press alerting system, in case a woman is hit on the head from behind, she may never get the chance to press panic button and no one will know she is in trouble. Our system solves this problem. This device is to be turned on in advance by a woman in case she is walking on a lonely road or some dark alley or any remote area. Only the woman authenticated to the devices can start the system by fingerprint scan. Once started the devices requires the woman to constantly scan her finger on the system every 1 minute, else the system now sends her location to the authorized personnel number through SMS message as a security measure and also sounds a buzzer continuously so that nearby people may realize the situation. In this case even if someone hits the woman or the woman falls down and get unconscious, she does not need to do anything, the system does not get her finger scan in 1 minute and it automatically starts the dual security feature. This device will prove to be very useful in saving lives as well as preventing atrocities against women. The device uses GPS sensor along with a gsm modem, lcd display, led’s and microcontroller based circuit to achieve this system.

This advanced project Fire Fighter Robotic Vehicle with Night Vision Camera allows a user to control a fire fighter robot equipped with water tank and gun remotely wirelessly for extinguishing fires. For this purposes the system uses an Rf remote for remote operation along with rf receive based microcontroller circuit for operating the robotic vehicle and water pump. The receiver circuit receives RF signals through RF based remote transfer users commands. The receiver circuit now decodes the data commands sent. It then forwards it to the microcontroller. Now the microcontroller processes these instructions and then instructions the vehicle motors to run the vehicle in desired directions. It also operates the water pump motor and pump direction motor to spray water based on users commands. This allows the user to operate the robot and put off the fire by standing at a safe distance. This robot body also has a wireless night vision enabled camera mounted over it. This night vision camera helps to direct the robot body in whichever direction as needed. This is because whatever area that will be captured by this wireless camera can be viewed in PC for reference. The robot operates within a 8 meter range of the remote. Thus this system helps to extinguish fire from a safe distance with the help of the water tank attached to the robot body.

An automated water pump system for farmers or any user needing it for filling tanks as well as for using water supply. The system consists of a pump motor along with LCD and gsm modem controlled by a microcontroller. The system allows users to remotely switch on/off motor as well as the system consists of an automated water sensing system that automatically switches off the pump motor as soon as it senses that water supply has stopped and the motor is on a dry run. Our system uses a GSM modem to send and receive user commands and it then operates the pump motor based on user SMS. The system also consists of IR sensors to detect water flow through the pipe as long as water flow is detected through pipe the pump motor runs. As soon as the sensor detects water supply has stopped the microcontroller is notified of the dry run condition. The system now notifies the user that it has shut down the motor on noticing dry run condition.

This system allows controlling a robotic arm by hand movements. This system uses RF receiver which is interfaced to the microcontroller which controls the driver IC which is responsible to control the movement of the arm. The transmitter circuit consists of an accelerometer sensor which is interfaced to the microcontroller. The transmitter circuit sends commands to the receiver circuit. This command indicates whether to move the robotic arm in upward or downward direction or whether the commands indicate to grip an object or release it.

We come across hospitals and NGO’s serving disabled people. Now these people are not capable of full body movement as compared to a normal person. In such a situation we propose a system that helps disabled person display a message by just simple motion of any part of his body. Our proposed system works by reading the tilt direction of the user part. This device needs to be mounted on user finger of hand. The user now just needs to tilt the device in a particular angle to convey a message. Tilting the device in different directions conveys a different message. Here we use accelerometer in order to measure the statistics of motion. It then passes on this data to the microcontroller. The microcontroller processes the data and displays the particular message as per input obtained. The microcontroller now displays the associated message on the LCD screen. It also sounds a buzzer along with message as soon as it receives motion signal from the accelerometer

Blind stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. The blind stick is integrated with ultrasonic sensor along with light and water sensing. Our proposed project first uses ultrasonic sensors to detect obstacles ahead using ultrasonic waves. On sensing obstacles the sensor passes this data to the microcontroller. The microcontroller then processes this data and calculates if the obstacle is close enough. If the obstacle is not that close the circuit does nothing. If the obstacle is close the microcontroller sends a signal to sound a buzzer. It also detects and sounds a different buzzer if it detects water and alerts the blind. One more feature is that it allows the blind to detect if there is light or darkness in the room. The system has one more advanced feature integrated to help the blind find their stick if they forget where they kept it. A wireless RF based remote is used for this purpose. Pressing the remote button sounds a buzzer on the stick which helps the blind person to find their stick. Thus this system allows for obstacle detection as well as finding stick if misplaced by visually disabled people.

We come across situations where we need to urgently need to display notices on a screen. For areas like railway stations and other such busy facilities the station master/announcer need not have to type in every announcement message manually on the screen. So here we propose an innovative android based notice display system that allows the user to display notices without typing them in manually. Here the announcer/administrator may speak out the message through his/her android phone, the message is then transferred wirelessly and displayed on the screen. To demonstrate this concept we here use an an LCD screen to display messages. The LCD is interfaced with an 8051 family microcontroller. We also use a Bluetooth receiver to get the android transmitted messages, decode them and send them to the microcontroller for further processing. The microcontroller then displays the message on the LCD screen. The entire circuit is powered by a 12 V supply through a transformer. This innovative system can be used in a variety of places including railway stations, schools, colleges, offices for displaying emergency announcements on the screen instantly by just speaking out the message instead of typing it in each time. So this is how voice based notice board project is very useful in various organizations.

The project is an electronic notice board that is controlled by an android device and displays message on it. Traditionally, there were notice boards where any information or notice had to be stick daily. This becomes tedious and requires daily maintenance. The project overcomes this problem by introducing an electronic display notice board interfaced to an android device through Bluetooth connectivity. The Bluetooth receives the message from the android device that is sent to a microcontroller. The microcontroller displays the message on a LCD screen. This project can be used in colleges, offices, railway stations or airports for displaying any information.

The project Voice controlled home automation project helps to control the electrical loads based on Bluetooth input signal. The Bluetooth device receives this input signal from android device. This system is especially beneficial in case of handicapped or aged people who find it difficult to walk and operate the electrical switches to turn on or off the loads. This system solves this issue as now the user just has to give voice commands to turn on or off the loads. Here 4 loads are used to demonstrate light, fan, heater and AC. All these loads can be individually turned ON/OFF or all loads at the same time. This system solves the issue by interfacing a unit with home appliances that switches these loads based on the input received from android device. The Android app also provides an effective GUI for providing this functionality. This system makes use of microcontroller. The Bluetooth receiver is interfaced with microcontroller in order to accept the commands and then react accordingly. It operates the loads through a set of relays using a relay driver IC. Relays are used between loads and the control unit. This system thus can be used in many domestic applications and in industrial setups.

The project aims at developing a speed control system for DC motors in four quadrants i.e. clockwise, anti-clockwise, forward brake and reverse brake. The project is useful to be used in industries for moving motors in both directions i.e. clockwise and anti-clockwise and can even apply forward and reverse brakes whenever required. The brakes functions by applying a reverse voltage in the motor for certain time. The speed is controlled by generating PWM pulses from microcontroller. A pair of push buttons is interfaced to microcontroller which is interfaced to operation motor by motor driver IC. The signals from the button are input to the microcontroller that in turn actuates motors in controlling speed.

The project is designed to find out the exact location of any vehicle and intimate the position to the concerned authority about through an SMS. This system includes a GPS modem which retrieves the location of a vehicle in terms of its longitude and latitude. This data is fed to the microcontroller which is interfaced with a GSM modem. Microcontroller retrieves the location details from the GPS and sends it to the concerned authority in the form of an SMS over GSM modem on periodical intervals so set by the user. An LCD display is interfaced to the microcontroller for crossing the data received before being sent over GSM Adopting this technology will be highly useful to transport companies to keep tracking their vehicles. This project can be further enhanced by making an arrangement to stop the vehicle ignition by the owner remotely by sending an SMS in theft situations

This system DC motor Controller by Android is developed to control the speed of the DC motor in both clockwise and anticlockwise direction. For this DC motor is interfaced to the 8051 microcontroller. A Bluetooth modem is used to receive direction commands and PWM commands. When an Android device sends commands, it is received by the Bluetooth modem which then sends the commands to the microcontroller. The microcontroller the controls the DC motor through motor driver. The entire system is powered by 12V transformer. LCD display is used to show the status and the speed of the DC motor. The android application is used to control the entire system. The start button is first clicked to start the motor and then the motor can run in both clockwise and anticlockwise direction. Simultaneously the status of the system is displayed on the LCD screen and also the speed of the DC motor is displayed on the screen. Thus the speed of the motor can be increased or decreased in clockwise or anticlockwise direction with the help of this android application.
