Abstract:

The Object of this project is to detect the speed of the vehicle and cutoff the fuel if it exceeds set speed. This project is designed with micro controller, Proximity Sensor asspeed sensor and driver circuit with Relay and keypad.In this project we are using Proximity sensor as a speed detector. A Proximity sensor can detect objects without physical contact. A proximity sensor often emits an electromagnetic field or beam and look for changes in the field. The object being sensed is often referred to as the proximity sensor's target. Here is an inductive proximity sensor, requires a metal target.The proximity sensor fixed near the wheel of vehicle to detect the sensor we fixed one plate on the wheel. When vehicle is traveling on the road proximity sensor crosses the plates and it gives the signal to micro controller.Except for the Autobahn in Germany, almost all roads have specific speed limits. And it is difficult for the driver to always look out for speed limits signs and adjust his speed accordingly. Over speed indicator is a device that tells the driver if he is exceeding the particular speed limit. With the over speed indicator in your car you can be sure that you are not going get yourself booked for over speeding. The system has a computer which stores the speed limits of different areas. The GPS in the system feeds the exact location of the car to the computer which looks up in its database to determine the permissible speed for the area and limits the car within the allowable speed.
