The purpose of this work is to avoid drunken driving accident by using alcohol detecting sensor. The uncontrolled many accidents were happened because of influence of alcohol during driving. To avoid such accidents, we have proposed alcoholic sensor in the vehicle ignition system. This system is integrating the alcohol sensor with microcontroller, relay switch and battery. The alcohol sensor used in this project is MQ-3 which detects the presence of alcohol content in human breath. Vehicle ignition system gets power from battery through relay switch. The ignition system will operate based on the level of Blood Alcohol Content (BAC) in human breath detected by the alcohol sensor and the signal will send to microcontroller, which will supply power to spark plug.
