Drunk driving continues to be a major cause of road accidents globally, leading to thousands of injuries and deaths every year. In fact, alcohol-related accidents contribute to approximately 2.3 million premature deaths annually. As we advance into a future where technology and safety are top priorities, an innovative solution to this critical issue is the Alcohol Detection System for Cars using the MQ3 sensor.

This system works by detecting the presence of alcohol in a driver’s breath and automatically preventing the car from starting if the alcohol concentration is above a predetermined level. By incorporating a simple circuit and MQ3 sensor, this system is designed to be reliable, efficient, and easy to implement. The system even includes rolling retests to ensure the driver remains sober throughout the drive.

Key Features of the Alcohol Detection System:

• MQ3 Sensor: A high-quality sensor that detects alcohol levels accurately.
• Real-time Alerts: Buzzer and LED indicators notify the driver of detected alcohol.
• Rolling Retests: Continuous monitoring of sobriety during the drive.
• 5V DC Power Supply: Operates efficiently with a regulated power system for better performance.
• Optimized for Indian Environments: Designed to work perfectly under local conditions.

This project is not just a solution for car owners, but a step toward enhancing road safety globally. Whether you are a DIY enthusiast or looking for a science project model, this system brings value to both educational and practical applications. With its ease of use, this system can be implemented into various vehicles, contributing to safer roads.
