The "Automatic Drunken Driving Detection System for Autonomous Vehicles" project offers a cutting-edge solution to combat the pervasive issue of drunk driving, a primary contributor to global road accidents. Our innovative approach integrates the MQ-3 Sensor, capable of identifying elevated alcohol levels within a vehicle. Upon detection, the system activates visual and auditory alerts, furnishing vital information to both the driver and passengers. Distinguishing our system is its ability to take pre-emptive measures, potentially averting accidents resulting from impaired driving. This initiative represents a significant advancement in reducing the dire consequences of drunk driving and fostering safer road environments. The ultimate objective is to save lives and prevent accidents.
