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.
Methodology of this Project:
1. Gas Sensing model
2. Driver unit
