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. Once she feels danger, she can press an emergency key and the system now injects chloroform with a high speed nozzle to the attacker and also sends lat/long value of that 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. 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 Bluetooth mdule, leds and microcontroller based circuit to achieve this system.

Note – Since this is a low cost prototype module, here we are using a Bluetooth device to send location, practically there will be a gsm modem.

The automotive are the present generation is highly sophisticated and equipped with manyelectronic systems to control and protect the Auto. The recent cars in the market equipped with systems such as alight bag protection, anti-skid protection, automatic wiper control, central locking system etc. These systems are electronic systems which are installed in the vehicles specifically highend four wheelers. These equipment are working on the basis of feedback from the sensors installed in the vehicles. There is acentral processor which is interfaced with different kinds of sensor andreceives the signal and processes it. The controller issue signal to different control units to act accordingly.

         
In this project we are using LIGHT transmitter sensors at the school college areain the both side of the gate and receivers in the vehicles. When the vehicles enter in the school area the LIGHT receiver sensor will activate and give asignal to the buzzer for an alarming sound as a result the driver will alertand drive the vehicle in a normal speed.

The Differential relay/theft protection is one of the relay, which basically designed to protect the power distribution line against earth fault or theft detection in a particular zone. The differential relay protects the zone of the transmission line.

The specialty in this project is the design is made on 89c51 micro controller, which is faster and controls the relay. This is static relay so no much mechanical movement is there. The response time is very fast and can be programmed from any value. The great advantage of programmability is available to the user.  This protection is developed on basic components. If the relay will be developed with same facility by electro mechanical component, then the cost and size of the device will be too high. The use of controller reduces extra hardware such as timers and connectors etc. The controller is embedded with all the components. The controller is the heart of the device and there are other hardware used for signal conditions and comparison. In this relay there are two current setting and it can hand maximum up to 15A current.

The mechanism used in the assembly is rack and pinion mechanism. It converts reciprocating motion into rotary motion. Here, the rack is the element producing reciprocating motion and pinion rotates due to this reciprocatingmotion. The rack is displaced vertically due to the weight of the vehiclepassing on the speed breaker and thus it reciprocates (M. Ramadan, et al,2015). As the rack reciprocates, it turns the pinion to rotate. The rack is the flat part which has teeth, while the pinion is a gear. 

Advantages of rack and pinion mechanism

• This assembly gives good mounting convenience.
• Gear losses are maximum up to 5%.
• Approximate efficiency of rack and pinion mechanism is about 95%.

In this project weare going to sense hand by using ultrasonic sensors. Basic principal of ultrasonic distance measurement is based on ECHO. When sound wavesare transmitted in environment then they return back to the origin as ECHOafter striking on any obstacle. So we have to only calculate its traveling timeof both sounds means outgoing time and returning time to origin after strikingon any obstacle by a 8051 microcontroller. And after some calculation we canget a result that is the distance. This concept is used in our tap controller project where the water motor pump is automatically turned on when hand comesnear to the tab. You can also check this simple water level indicatorcircuit for a simpler version of this project. Here the pump is controlled through a solid state relay. Ultrasonic sensor is the input device and LCD relay is the output device. This setup is placed on a fabricated stand.

Thetechnology of pneumatics plays a major role in the field of automation andmodern machine shops and space robots.. The aim is to design and develop acontrol system based intelligent electronically controlled automotive breakactivation and automatic braking system is called Automatic Pneumatic Breakactuation Before Collision. This project consists of Ultrasonic transmitter andReceiver circuit, Control Unit, Pneumatic break system and pneumatic brakingsystem. The ultrasonic sensor senses the obstacle. There is any obstacle closerto the vehicle (within 3-4 feet), the control signal is given to the break activationsystem and also pneumatic braking system simultaneously. The pneumatic breakand braking system is used to product the man and vehicle. This break andbraking activation system is only activated the vehicle speed above 30-40 kmper hour. This vehicle speed is sensed by the proximity sensor and this signalis given to the control unit and pneumatic break and braking activation system.

The project uses a digital temperature sensor for precise control of temperature in medical applications or industries. This system is better than analog/thermostat system, which has poor accuracy. For example, it can used for temperature control of an incubator where maintaining a precise temperature is very important. An incubator is an apparatus used to maintain temperature conditions suitable for a neonate (newborn baby) and used particularly for preterm births of babies. This proposed control system provides the temperature information on a display and, when the temperature exceeds the set point, then the load (i.e. heater) switches OFF. In this project a lamp is provided as a load for demonstration purpose.

IOT based LPG leakage detection system senses the LPG gas with the help of an LPG gas sensor. LPG gas sensor interfacing with nodeMCU is implemented in this project. The Signal from this sensor is sent to the Analog input A0 of the nodeMCU. The nodemcu is connected to an LCD with i2c module, Buzzer and moor driver. This WiFi module which is used for connecting to Wi-Fi network and make TCP/IP connections and send data. Data, which is sensed by these sensors, is then sent to the IOT.  The IOT module then sends the data over to a website. Once the gas leakage is detected, the buzzer and fan  is turned ON and a ‘Leakage detected’ message is displayed on the LCD. The Pre-requisite for this LPG gas leakage detection and the smart alerting project is that the Wi-Fi module should be connected to a Wi-Fi zone or a hotspot.

Automatic load shedding in transformer

The project is an automatic load operation system that controls load operation, multiple numbers of times according to programmed instruction. The project eliminates the manual ON/OFF switching of load. A real time current sensing device is used to measure the current and automatically switch ON/OFF the load sequentially. This project is required for load shedding time management which is used when the electricity demand exceeds the supply and there comes a need for manually switching ON/OFF the electrical devices in time. Hence this system eliminates the manual operation by automatically switching the load ON/OFF.  This is a best project on electrical engineering students. To attain our concept, need to use Atmega328p controller, Relays, current sensor, buzzer, LCD, step-down transformers and towers. The fault occurring is displayed on a 16X2 LCD interfaced with the microcontroller.
