Alcohol Detection system and smart engine lock

Traffic accidents are a major cause of fatalities, with drunk driving and negligence being the main causes. To combat this issue ,this project uses an alcohol detecting sensor in vehicles for safe driving, detecting alcohol particles and sending messages if needed. A microcontroller-based system sets and monitors two Blood Alcohol Content (BAC) thresholds, transmitting driver's BAC level and vehicle position to a central monitoring unit, and shutting down the engine at the second threshold.
