Introduction
The Alcohol Detection Car Safety System is a life-saving innovation designed to prevent drunk driving-related accidents. This project, ideal for EEE final-year students, integrates Arduino, an MQ-3 alcohol sensor, a relay module, and a servo motor to detect alcohol levels and prevent the car from starting if the driver is intoxicated.
This system is a cost-effective and practical solution that can be implemented in real-world vehicles to improve road safety.
Why is the Alcohol Detection Car Safety System Important?
Drunk driving is a leading cause of road accidents worldwide. According to the World Health Organization (WHO), nearly 1.3 million people die in road accidents annually, and a significant percentage of these are due to drunk driving.
🚗 Key Benefits of the Alcohol Detection Car Safety System:
- Prevents drunk drivers from starting the vehicle.
- Reduces road accidents caused by alcohol consumption.
- Enhances vehicle safety through automation.
- Encourages responsible driving habits.
This smart embedded system ensures that only sober drivers can start the vehicle, making roads safer for everyone.
Components Used in the System
This project utilizes Arduino-based automation with the following key components:
| Component | Function |
|---|---|
| Arduino UNO | Microcontroller that controls the entire system. |
| MQ-3 Alcohol Sensor | Detects alcohol levels in the driver’s breath. |
| LCD Display (16×2) | Displays system messages like “Alcohol Detected”. |
| Relay Module | Controls the ignition system based on alcohol detection. |
| Servo Motor & Wheel | Simulates the engine start/stop mechanism. |
| 5V 5A SMPS | Provides power supply to the components. |

How the Alcohol Detection Car Safety System Works
This system follows a step-by-step process to ensure driver safety:
- Driver breathes near the MQ-3 alcohol sensor.
- Sensor analyzes the breath and determines the alcohol concentration level.
- If the alcohol level exceeds the threshold, the system triggers a warning on the LCD.
- Relay module prevents ignition activation, stopping the car from starting.
- If alcohol is not detected, the vehicle starts normally.
🔧 Smart Feature: If alcohol is detected while the car is running, the system can gradually slow down the vehicle to ensure safe stopping.
