Obstacle and Air Quality Detection and Avoidance of Accidents.

The basic idea of the project is to prevent the increasing rate of accidents in cities like Delhi. As soon as an obstacle is detected, the ultrasonic sensor senses it and calculates the distance of obstacle from the vehicle. Then the vehicle will start or stop through motors which are connected through the relay. It also consists of an air quality sensor which would sense the smog and also provide details like it’s density and percentage. As soon as the smog density rises above the critical limit, it would send a signal to the microcontroller to increase the intensity of headlights.
