Abstract:

Alcohol-related accidents are a significant concern, with 2.3 million premature deaths reported annually due to harmful alcohol consumption. The Smart Automobile Off System by Alcohol Detection DIY STEM Kit is designed to mitigate these risks by integrating an alcohol detection mechanism into automobile ignition systems.

Using the MQ3 Alcohol Sensor, this system detects alcohol content in a driver’s breath and prevents vehicle ignition if alcohol is detected. It also incorporates rolling retests to ensure continued sobriety while driving. This innovative solution is ideal for educational projects, automation systems, and promoting road safety.

Working:

The system uses the MQ3 sensor to detect alcohol vapors in the air. When alcohol molecules are present, the sensor outputs a voltage based on their concentration. This triggers a buzzer and LED, providing an alert. The sensor works on 5V DC, regulated by the IC 7805 for stable operation.

The circuit can also be used by law enforcement officials to prevent drunk driving. It offers a practical, hands-on learning experience for students and enthusiasts exploring electronics and safety automation.

Key Features:

• Assembled & Tested: Ready-to-use kit with high reliability.
• Educational Value: Excellent for STEM learning, DIY experiments, and automation projects.
