Automatic Engine Locking System Through Intoxicant and Accident Detection using Arduino

Equipment Used :

1. Arduino UNO

2. MQ3 Alcohol Sensor

3. DC motor

4. Vibration Sensor

5. LCD Display

6 .GSM Module

7. GPS Module

Objectives :

• Most of these days, we hear lot of accidents due to drunken driving. Drunken drivers will not be in stable condition. so the rash driving is the inconvenience for other road users and also question of life and death for the drunken driver and for other.
• To protect life against drunken drive accidents this project is helpfull. Alcohol Detector in Car projected and designed for the safety of the people seating inside the car.
• By implementing this design a safe car journey is possible and also drunken drivers can be controlled.
• The system implemented by us aims at reducing the road accidents in the near future due to drunken driving. The system detects the presence of alcohol in the vehicle and immediately locks the engine of the vehicle.
• At the same time an SMS along with the location of the vehicle is send to three pre-selected contacts.

Working :

• In this project, Arduino is Heart. It operates and control the MQ3 Sensor and Vibration Sensor

• MQ3 sensor is used for detecting the alcohol consumption by the driver if alochol is detected the MQ3 sensor will send signal to arduino.

• Vibration sensor is used for detecting accident or sudden change in any axis. And an optional LCD is also used for displaying status messages or coordinates. 

• Our system is powered with a 9V battery. A 5V DC supply as required by the micro-controller, sensor and display unit. While other components like DC motor require 1.5V and the LED's need 2V.

• This study develops a prototype alcohol detection and engine locking system by using an Arduino Uno micro-controller interfaced with an alcohol sensor along with an LCD screen and a DC motor to demonstrate the concept.

• The system uses MQ-3 alcohol sensor to continuously monitor the blood alcohol content (BAC) to detect the existence of liquor in the exhalation of a driver. By placing the sensor on the steering wheel, our system has the capacity to continuously check alcohol level from the driver’s breath.

• The ignition will fail to start if the sensors detects content of alcohol in the driver’s breath. In case the driver got drunk while driving, the sensor will still detect alcohol in his breath and stop the engine so that the car would not accelerate any further and the driver can park by the roadside.

Block Diagram :

The block diagram of the proposed system is shown in figure 1. It consists of power supply section, MQ-3 alcohol sensor, DC motor, LCD, micro-controller, alarm and LED's.
