Safetronic technology in automobiles using ultrasonic sensor

ABSTRACT Accident will occur every time and everywhere and cause worst damage, serious injury and dead. Accidents are caused mostly due to the delay in applying of brakes and the wrong decisions taken by the driver like opening the doors at the wrong time and place. This work is designed to develop a new system that can solve this problem where drivers may not brake manually but the vehicles can stop automatically due to obstacles and locks the door at the extreme rear collision scenarios. This work is about a system that can control the central locking system of the car. Using ultrasonic transducer as a ranging sensor, its function based on ultrasonic wave After transmit by transmitter, the wave can reflect when obstacle detected and receive by receiver.
