Abstract

This project presents the design and simulation of an alcohol sensing system integrated with an engine locking mechanism to mitigate accidents caused by drunk driving. The system employs an MQ-3 alcohol sensor interfaced with an Arduino Uno microcontroller to monitor the driver’s breath for alcohol concentration. When the detected level exceeds a defined threshold, the system prevents the engine from starting or shuts it down to restrict further vehicle operation. Supporting units include a display for user feedback, indicator LEDs, and an alarm to alert passengers. Circuit simulations conducted in Proteus software confirmed the system’s ability to accurately detect alcohol levels, respond within acceptable timeframes, and reliably trigger the locking mechanism. The design prioritizes accuracy, dependability, low power consumption, and user-friendliness. Results demonstrate that this technology can significantly reduce the risk of drunk-driving incidents, enhance road safety, and encourage responsible driving behavior. Furthermore, the study contributes a practical framework for future advancements in intelligent vehicle safety systems.
