Engine Locking Feature Enabled Alcohol Sensing Alert System

Abstract

This paper aims to reduce the number of accidents caused by drunk drivers and to make driving safer for everyone. Drunk driving has become a major problem and has claimed the lives of many people. A driver who was intoxicated put himself and other people in danger. Thus, we are putting forth an original and cutting-edge method to lower the number of accidents brought on by drunk drivers. The suggested system states that the car operates on its own and that a driver is not allowed to operate a vehicle after drinking. We are using an Arduino UNO, a DC motor, a relay, and an alcohol detection sensor (MQ-3). The system aims to create a safe environment for the occupants of the car and those around it. The proposed architecture is embedded in a vehicle to lock the engine when the driver is in a drunken state which plays a key role in real-time.
