Vehicle ignition override system to avoid drunken drive

Abstract

Safety is one of the very important aspects while driving. Drunken driving can cause accidents of higher intensity with a huge damage to the vehicle and the people travelling in it. In this paper we propose a vehicle ignition override mechanism that will help in avoiding drunk and drive accidents to a huge extent. We propose a system that uses an ethyl alcohol sensor more commonly known as alcohol sensor to detect the presence of alcohol in the driver’s breath and a pulse sensor to collect the heart rate of the driver. The system is controlled by a microcontroller which is also interfaced with GPS and GSM modules to send the details of the location of the car to the emergency contacts and owners in case of rented cars. Also, the main aim of the proposed system is to switch of the car engine to avoid any further damage to the life.
