Automatic Alcohol Detection System Using Microcontroller

Abstract

The purpose of this project is to detect whether a person is in the state of driving a vehicle and develop vehicle accident prevention to reduce accident under the influence of alcohol or due to drowsiness. This project is developed by interfacing the alcohol sensor and eye blink sensors with the microcontroller AT8C952. Further a Gsm is used for alerting the driver's relative or the traffic controller police that the person is in drunken state. The alcohol sensor used in this project is MQ-3 which is used to detect the alcohol content in human breath. A motor is used as a prototype to act like a vehicle’s engine. The ignition system will operate based on the level of blood alcohol content (BAC) from human breaths detected by alcohol sensor.The main purpose behind this project is “Drunk driving detection”. Now a days, many accidents are happening because of the alcohol consumption of the driver. Thus Drunken driving is a major reason of accidents in almost all countries all over the world.This project should be installed inside the vehicle.
