This project is developed for the users to identify his vehicle if someone uses his car.
It consists of a door sensing unit, a RF transmitter at the device and RF receiver at the hand set, controlling unit and telephone circuit.
The sensor is connected at the door. When the owner of the car locks the door, he has to switch on the security device. If some one opens the door, it sends signal to the controlling unit in the device.
