Arduino Based Alcohol Sense Engine Lock Using GPS & GSM Module with Ardiuno

This project is a safety system designed to prevent drunk driving by integrating alcohol sensing technology with an engine lock mechanism. The system utilizes an Arduino microcontroller to interface with an alcohol sensor, GPS module, GSM module, and other components to enhance safety and functionality.

Features:
Alcohol Detection:

Equipped with an MQ-3 alcohol sensor to detect alcohol levels in the driver's breath.
If alcohol levels exceed a predefined threshold, the engine lock system is activated.
Engine Lock Mechanism:

Automatically disables the vehicle's engine if alcohol consumption is detected.
Ensures that the vehicle cannot be started until alcohol is no longer detected.
GPS Tracking:

A GPS module tracks the vehicle's real-time location.
Location data is used to monitor and respond to incidents effectively.
GSM Alerts:

Sends SMS alerts to a predefined emergency contact when alcohol is detected.
Alerts include the location of the vehicle, enabling quick response in emergencies.
User-Friendly Interface:

Simple system configuration using Arduino IDE.
Easy to set up and calibrate the alcohol sensor.
Applications:
Preventing drunk driving accidents by stopping intoxicated individuals from operating vehicles.
Enhancing vehicle safety with real-time tracking and alert systems.
Useful for fleet management, school buses, and public transportation systems to ensure driver sobriety.
Components Required:
Arduino Uno or compatible microcontroller
MQ-3 alcohol sensor
GPS module (e.g., NEO-6M)
GSM module (e.g., SIM900A)
Relay module for engine lock
Power supply and connectors
Buzzer and LED indicators for local alerts
Workflow:
The alcohol sensor continuously monitors the driver’s breath for alcohol.
If alcohol is detected, the Arduino processes the sensor data and triggers the engine lock relay.
Simultaneously, the GPS module collects the vehicle's location, and the GSM module sends an SMS alert.
A buzzer and LEDs provide immediate local notification of the detected alcohol levels.
