The current investigation is to epitomize the technical work in the form of project which illustrates how human driving can be made safer so to avoid accidents and make the roads safer to drive for the driver & also the commuters. The work is developed by integrating sensors based on alcohol content detection conglomerating with Microcontroller board like Arduino, ATmega328 is more versatile in handling more functions than any other conventional microcontroller. The MQ3 module is used to detect the alcohol particle which has reasonable sensitivity range around two meters, and is suitable for any kind of vehicle. The sensor has one more unique quality that it can simply be unseen from the defendants. It is too compact to fit complete set up in the form of product in automobile.
