Abstract:
It is a common observation that smokes, fog or the negligence of drivers results in road
accidents. I have a designed a system that is efficient enough to sense any obstacle, the motion of
the car which is coming in front of it. So therefore ultrasonic sensors are used to serve this
purpose as they work efficiently in fog, smoke and light and its signal is 40khz which means that
it is not audible to human ear. I have interfaced two vehicles A and B with a microcontroller
along with ultrasonic sensors. The time in which we get a signal from car B that is coming in the
opposite direction of car A, the microcontroller will buzz the alarm in car A if car B is in the
range of 5 feet. As I m giving a demo in room therefore I have selected this range but in real life
this distance can further be elongated to 25 feet. If car A will not stopped by driver’s misconduct,
it will automatically switched off within few seconds i.e 1 to 2 seconds.
