Automatic fire alert system for automobiles is a system which can sense the presence of fire and smoke and generate a series of alarm driven events after it. When the fire is detected it turns on a motor which is depicted in the project as breaking mechanism. Thus by this the car can be stopped and the passengers and other payloads can be safeguarded thereafter. Along with breaking, the system sounds a buzzer that would alert nearby people around it so that they can be cautious about the presence of fire in the vehicle. Also, an SMS is sent to the Fire safety Authorities which will help them to take quick decisions to take control of the fire. Hence this project offers a very robust mechanism for safety in the vehicles which works automatically with the help of microcontrollers and sensors.
