Intelligent Alcohol Detection System for CAR

Published on Dec 05, 2016


This is used to Sense and drive the relay for ignition on/off for drug drive control system.


This system will sense the alcohol level of human body through sensor and control the drive to avoid accident.

 To enter the gas of alcohol level through key pad

 Then automatically the circuit will sense the alcohol and active the relay of ignition

 The ignition is connected to relay will control through microcontroller.

 All the level will display on the LCD.
