DOr develop prevention of vehicle accidents by alcohol detection method in an effort to reduce cases of traffic accidents based on driving under the influence of alcohol. This project is developed by integrating the alcohol sensor with the 16F877A micro-controller. The alcohol sensor used in this project is MQ-2 which detects the alcohol content in human breath. An ignition system that will produce spark plugs is accumulated as a prototype to act as the ignition starter on the vehicle's engine. The ignition system will operate based on the level of blood alcohol content (BAC) of human breaths detected by the alcohol sensor. The main purpose behind this project is "rubber driving detection". Now one day, many accidents are happening due to the alcohol consumption of the driver or the person who is driving the vehicle. Thus, drunk driving is one of the leading causes of accidents in almost every country in the world. Alcohol Detector in Car project is designed for the safety of people sitting inside the car.
