Alcohol Sensing with Engine Locking System and Communication Using GPS GSM Technology

This research presents the design and implementation of an integrated safety system for vehicles aimed at enhancing road safety, deterring impaired driving, mitigating rash driving behaviors, and preventing vehicle theft. The alcohol detection component utilizes an MQ3 sensor to accurately measure alcohol concentration in the driver's breath. When the concentration exceeds predefined thresholds, the system triggers appropriate responses, including engine immobilization and alerts. Rash driving behaviors are detected using accelerometers and gyroscopes, which analyze vehicle motion data in real-time. An engine locking mechanism immobilizes the vehicle's engine in response to detected alcohol presence or rash driving behaviors, enhancing safety and preventing further operation of the vehicle. GPS tracking enables real-time monitoring of the vehicle's location and transmission of location data to designated contacts or authorities in emergencies, accidents.
