This is a motorized fire safety science project for school children. For this, a car is built with four small DC motors and a nine volt battery and a sensor connected to it that detects a fire. This is a great idea and project for science kids. It can be made at home.


When the light comes near the photo diode, a voltage is generated in it and that voltage is boosted by IRF and fed to the motor. At that time, the motor moves and helps the car move away from the fire.
