Drunken Driving Detection Using Car Ignition Locking

Drunk driving is the reason behind most of the deaths, so the Drunk Driving Detection with Car Ignition Locking Using Arduino aims to change that with automated, transparent, noninvasive alcohol safety check in vehicles. The system uses Arduino with alcohol sensors, dc motor, and LCD display circuit to achieve this purpose. System uses alcohol sensor with, raspberry pi with dc motor to demonstrate as vehicle engine. System constantly monitors the sensitivity of alcohol sensor for drunk driver detection. If driver is drunk, the processor instantly stops the system ignition by stopping the motor. If alcohol sensor is not giving high alcohol intensity signals, system lets engine run. The Arduino controller constantly processes the alcohol sensor data to check drunk driving and operates a lock on the vehicle engine accordingly.
