Our innovative Arduino-based alcohol detection and engine lock system is designed to enhance road safety by preventing impaired driving. Here’s a detailed look at how our system works and its key features: 

How It Works

• Alcohol Detection: The system uses a high-precision sensor to measure the driver’s blood alcohol content (BAC).

• Real-Time Analysis: The sensor provides real-time data to the Arduino microcontroller.

• Engine Lock Mechanism: If the BAC level exceeds the legal limit, the microcontroller activates a relay that locks the vehicle’s engine, preventing it from starting.

• GPS Location Tracking: Integrated GPS module tracks vehicle's current location in real-time.

• Location-Based SMS: Sends SMS with current GPS coordinates to predefined contacts in case of alcohol detection and engine lock activation.

• Safety Assurance: Only when the driver’s BAC is below the threshold will the engine unlock, ensuring that only sober individuals can operate the vehicle.

Key Features

• High Sensitivity Sensor: Accurately detects even low levels of alcohol in the breath.

• Real-Time Monitoring: Continuously monitors and analyzes BAC levels.

• Automatic Engine Lock: Proactively locks the engine if the BAC is above the legal limit with the use of relay modules.

• Immediate location sharing system: Sends an immediate message warning the relatives along with the exact location coordinates.

• User-Friendly Interface: Simple and intuitive design for ease of use.

• Compact and Durable: Designed to withstand various environmental conditions.

Benefits

• Enhanced Road Safety: Reduces the risk of accidents caused by impaired driving.

• Peace of Mind: Provides assurance to families and fleet operators that drivers are sober.

• Compliance: Helps drivers adhere to legal alcohol limits.

• Cost-Effective: A smart investment in safety with long-term benefits.

Application

• Personal Vehicles: Ensures family members are safe and responsible on the road.

• Commercial Fleets: Ideal for companies to monitor and manage driver sobriety.

• Public Transportation: Enhances the safety of passengers by ensuring drivers are sober.
