Alcohol Detection

Nowadays many accidents are happening because of the alcohol consumption of the driver or the drunk person is driving the vehicle by self. The drunk driving vehicle is a major reason for accidents in most countries all over the world.

In this project, we are going to design alcohol detection inside the Vehicle. Alcohol sensor is placed near to the steering so that it can sense the alcohol consumption of the driver.

You need the Arduino Uno Board to be used as the controller, DC Motor used as instead of vehicle and buzzer can be used to indicate that driver had drunk.

Project Description:

1. Arduino: The digital and analog input/output pins equipped in this board can be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
2. DC Motor: This is an electric machines which converts electrical energy to mechanical energy.
3. Buzzer: A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short).Tt voltage is 5v DC supply
4. MQ135: The MQ135 sensor senses the gases like ammonia,nitrogen,oxygen,alcohols,sulfide and smoke. The operating voltage of this alcohol sensor is 2.5v to 5.0v

Project Implementation:

1. Interface Alcohol Sensor, DC Motor and Buzzer with Arduino
2. Power the components and upload the code to Arduino Uno Board
3. Keep the normal Marker Pen near to the sensor,alcohol sensor detects it,the DC Motor stops and buzzer ON

Software requirements:

1. Arduino IDE: You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
2. Programming language: C++ language
