Alcohol Detection System with Vehicle Control

The Alcohol Detection System is an innovative safety solution for vehicles designed to reduce drunk driving incidents. By integrating an alcohol sensor with vehicle control systems, it ensures that the driver’s sobriety is checked before starting the vehicle. If alcohol is detected, the system disables the vehicle’s ignition and activates safety alerts.

Improved Road Safety

1. Prevents intoxicated drivers from operating the vehicle, significantly reducing the risk of accidents caused by impaired driving.
2. Protects not only the driver but also passengers, pedestrians, and other road users.

Specifications:

1. Core Functionality:
   • Detects alcohol levels using a precise alcohol sensor (e.g., MQ-3).
   • Prevents vehicle ignition when alcohol presence exceeds a predefined limit.
   • Triggers an audible alarm and visual indicators to alert the driver and nearby individuals.
2. Components:
   • Alcohol Sensor: Highly sensitive to alcohol vapors, providing accurate detection.
   • Microcontroller (e.g., Arduino Uno): Processes sensor data and controls output signals.
   • Relay Module: Manages the ignition system, enabling/disabling vehicle start.
   • Buzzer: Emits loud audible alerts when alcohol is detected.
   • LED Indicators: Provide visual alerts for system status and detection.
   • Gear Motor and Wheels: Simulates vehicle motion, showcasing control mechanisms during testing.
3. Power Supply:
   • Operates on a 9V battery or vehicle power system (DC supply).
   • Low power consumption for efficient performance.
4. User-Friendly Design:
   • Compact and easy to install in vehicles.
   • Real-time alcohol detection with immediate response.
5. Safety Features:
   • Ensures that the ignition remains locked until the alcohol level is below the set threshold.
   • Prevents misuse by restricting functionality if tampered.
