Description

The Alcohol Sensor Engine Lock System is designed to enhance vehicle safety by preventing operation under the influence of alcohol. The system uses an MQ-3 alcohol sensor to detect the presence of alcohol in the breath of the driver. If alcohol is detected, the system prevents the engine from starting by controlling an engine lock mechanism via a relay module and a DC motor. This solution integrates with Arduino Uno for processing sensor data and managing output controls.

Benefits

  1. Enhanced Road Safety: Prevents accidents by ensuring drivers are sober before starting the vehicle.
  2. Prevention of Drunk Driving: Deters drunk driving through automatic detection and engine lock functionality.
  3. Easy Integration: Can be installed in various vehicle models without extensive modifications.
  4. Immediate Alerts: Buzzer and LED indicators notify the driver when alcohol is detected.
  5. Cost-Effective: A simple, affordable solution for personal and commercial vehicle safety.

Working

  1. Alcohol Detection: The MQ-3 alcohol sensor detects alcohol levels in the driver’s breath when they blow into it.
  2. Signal Processing: The Arduino Uno processes the sensor data and checks if the alcohol concentration exceeds a predetermined threshold.
  3. Engine Lock Control: If alcohol is detected, the Arduino sends a signal to the relay module to activate the DC motor, which locks or disables the engine ignition system.
  4. Alert System: The system triggers a buzzer and LED indicators to alert the driver that alcohol has been detected.
  5. Power Supply: A 12-0-12 transformer, rectified by diodes and regulated by a 5V voltage regulator, ensures stable power for the system.
  6. Manual Override: The push button switch can be used for emergency override (e.g., for maintenance purposes).

Components

  1. Arduino Uno: Main microcontroller for processing sensor input and controlling outputs.
  2. MQ-3 Alcohol Sensor: Detects the presence of alcohol in the air.
  3. Relay Module: Controls the connection between the engine system and the locking mechanism.
  4. Buzzer: Provides an audible alert when alcohol is detected.
  5. DC Gear Motor: Used to activate the engine lock.
  6. DC Jack: Provides the power supply connection.
  7. Soldering Iron and Soldering Wire: Used for assembling and connecting components.
  8. Connecting Wires: For making electrical connections between components.
  9. Carbon Resistor: Limits current flow to protect components.
  10. LED Indicators: Display status (e.g., alcohol detected or engine locked).
  11. Electrolytic Capacitor: Helps stabilize the power supply.
  12. Push Button Switch: Used for manual override or testing.
  13. 12-0-12 Transformer: Step-downs AC voltage for power supply.
  14. Diodes: Used for rectification to convert AC to DC.
  15. 5V Voltage Regulator: Provides a stable 5V supply to the Arduino and sensors.
  16. AC Motor: Can be used as part of the engine locking system.

This Alcohol Sensor Engine Lock system provides a practical, safety-focused solution for reducing the risk of drunk driving.
