This leads to severe accidents as such that happened in Delhi in which a car ran over four road dwellers killing them on the spot. So there is a necessity to develop an efficient alcohol detection system.

The Driver Alcohol Detection Systems for Safety, as the new approach is called, would use sensors that would measure blood alcohol content in one of two possible ways: * analyzing through driver’s breath

* analysing through the skin
These techniques using sophisticated touch-based sensors placed strategically on steering wheels and door locks. ANALYZING THROUGH BREATH:
This technique uses breathalyser to measure the concentration of alcohol in air exhaled by an individual. Here the first public demonstration of systems that could measure whether a motorist has a blood alcohol content at or above the legal limit of 0.08 BAC(Blood Alcohol Content) and, if so it prevent the vehicle from starting. The standard rate of alcohol leaves the body is normally 0.015 BAC per hour. There are three types of...
