Driving Under the Influence (DUI) significantly threatens human life and public safety. With an increased number of vehicles on the roads, manual checking for cases of drunk driving using breathalyzers becomes ineffective. In-vehicle alcohol detection using various IoT technologies prevents road accidents and makes driving a secure experience. The system integrates alcohol sensor MQ3 with microcontrollers, for example - Arduino Uno to detect the level of Blood Alcohol Content (BAC). Additional components such as transdermal sensors, nano sensors, and eye-blink sensors can also be used to measure the level of drowsiness. This system is adaptive, compact, inexpensive, and easily installed in all vehicles without driver suspicion. As a precautionary measure, if the alcohol concentration surpasses the threshold value, then the ignition system automatically gets turned off. The concerned authorities are simultaneously alerted using a GSM module. An announcement framework and an auto-fine collection system can also be developed and integrated into this circuit.
