Now a day's every system is automated in order to face new challenges. In the present days Automated systems have less manual operations, flexibility, reliability and accurate. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. The purpose of this project to develop vehicle accident prevention by method of alcohol detector in an effort to reduce traffic accident cases based on driving under the influence alcohol. This project is developed by integrating the alcohol sensor with the Arduino Uno. MQ-3 is used to detect the alcohol content in human breath and display the breath value on LCD display. IR sensor is used to detect the person. An ignition system automatically turns OFF the vehicle motor if the driver is alcoholic.
