Abstract

To combat the widespread problem of drunk driving, this study integrates an alcohol sensor with a motor control system in vehicles. By automatically modifying the motor's movement in response to the driver's blood alcohol content (BAC), the goal is to improve road safety. The system measures the BAC in the car using a MQ-3 alcohol sensor and an Arduino UNO microcontroller. The motor will stop and prevent driver from running the vehicle if the BAC is higher than the set level which 0.08% following Malaysia legal restriction. Drivers may disable the system by pushing a push-to-off button if their high tolerance for alcohol leads the system to incorrectly indicate them as intoxicated. The process includes configuring hardware and using the C++ programming language. The system's effectiveness in detecting alcohol levels and its potential to reduce drunk driving are demonstrated by result findings. 40% alcohol-content liquor was used for the sensor's calibration in either direct and breath. Breath and direct are measured at 435 ppm and 645 ppm. The direct reading is higher than the breath reading theoretically proves how effective the sensor functions.
