Automatic Drunken Drive Avoiding System

Abstract

The project entitled Automatic drunken drive avoiding system is designed for the users to use vehicles only when they are free from drinks (Alcohol). The main parts in this project are Alcohol sensor, Vehicle motor, Microcontroller and electronic circuit. The Alcohol sensor senses the presence of Alcohol. If the user uses alcohol, the sensor sends signal to the microcontroller. The microcontroller analyses the signal and sends signal to the electronic circuit. The electronic circuit breaks the power connection to the spark plug. Thus the user can not start the vehicle. If the user is free from alcohol, the power connection to the spark plug will be ok and thus the vehicle will be started easily.
