Drunk and Drive Detection System for Safety Driving

Drunk and drive is leading cause of road accidents and it is the major reason behind most of the demises. The method of manual checking or scanning the vehicle drivers by using breath analyzers increasingly difficult for traffic cops. To avoid the difficulty of traffic cops, the automated drunk and drive, accident detection system with ignition lock was implemented by using Raspberry PI PICO. It aims to change with automated transparent, noninvasive alcohol safety check in vehicles. This system uses alcohol sensor MQ3, MEMS sensor, DC Motor, GSM module. GSM module locates the site of accident and correspondingly informs to the nearest person through a text message. The proposed system constantly screens the sensor output to know whether the driver was consumed alcohol or not. If driver was found to be drunk, the Raspberry PI processor instantaneously halts the vehicle ignition by stopping the DC motor otherwise the engine will run accordingly. The system also detects the vibrations of vehicle through MEMS sensor which was placed near the engine. Once the accident detects by MEMS sensor, GSM module activates to send SMS alert about the location and condition of vehicle to registered mobile number. When accident occurs, the airbag will open to save the life of the driver. In the place of airbag, LED was used. If LED glows means, airbags will open.
