Introduction

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

Objective:

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.

Methodology of this Project:

1. Gas Sensing model
2. Driver unit
