Live Demonstration of Alcohol Prototype for Drunken Drive Case

Abstract

In recent times ‘drink and drive’ is one of the major causes for highway accidents. These types of accidents occur due to drowsiness when the drunk driver is unable to control the vehicle. Alcohol breathalyzer is one of the essential devices which uses non-invasive technique to measure the content of alcohol in human breath and correlates to the alcohol concentration in the blood. As per the National and International standards, a driver is found guilty if the alcohol content in his breath is found to be ≥ 700 ppm. It is therefore, required for this sensor to be efficiently detecting alcohol in low levels at room temperature. Apart from this, few other desirable parameters of a sensor are selectivity, stability, repeatability and low power consumption. In this demo, we will demonstrate a real-time lab prototype which will detect level of alcohol in human breath. This kind of device will be extremely useful to traffic police for keeping vigilance on drink and drive cases.
