Abstract
The alcohol detection and engine lock system is an innovative safety solution that integrates an Arduino Uno and an MQ-3 alcohol sensor to prevent drunk driving. The system operates by measuring the drivers breath for alcohol concentration before starting the vehicle. The MQ-3 sensor, which is sensitive to alcohol, detects ethanol levels in the air. If the alcohol concentration exceeds a specified threshold, the Arduino Uno activates a relay that triggers an engine lock mechanism, preventing the vehicle from starting. This system not only ensures that intoxicated drivers are unable to operate the vehicle, but it also serves as a deterrent to driving under the influence. Designed for simplicity and affordability, this alcohol detection and engine lock system can be installed in various types of vehicles, potentially reducing the risk of accidents caused by impaired drivers and contributing to safer roads for all users.
