Alcohol Detection with Black Box System

Abstract

This system provides a novel technique to curb drunken individuals. The system has an alcohol device embedded on the steering of the automobile. Whenever the driving force starts ignition, the device measures the content of the alcohol in his breath and mechanically switches off the automobile if he's drunken. During this system the device delivers a current with a linear relationship to the alcohol molecules from zero to terribly high concentration. The output of the device is fed to the picmicrocontroller for comparison. If the measured worth reaches the brink, relay bring to an end mechanically and also the buzzer produces sound.
