Alcohol Sensing Alert with Engine Locking System Using Arduino, GPS, and GSM

This project presents an automated Alcohol Sensing Alert and Engine Locking System designed to prevent drunk driving and enhance road safety. Using an Arduino microcontroller, MQ-3 alcohol sensor constantly monitors the driver’s breath for alcohol content. If the system detects alcohol levels exceeding a preset threshold, it immediately sends an SMS alert with GPS coordinates to predefined contacts using GSM and GPS modules. Simultaneously, the system locks the vehicle’s engine to prevent ignition or stops the engine if already running. The setup includes an LCD display for real-time feedback and buzzer alerts for immediate warnings. This smart integration offers a reliable solution to reduce accidents caused by drunk driving.
