Abstract

In 1987, the Malaysian government passed the Road Transport Act 1987 where it is considered an offence when a person drink and drive. Through decades of research, it is concluded that drink-drivers have a higher risk of being involved in a traffic accident than non-drinking drivers. Hence the need for prevention of these accidents should be enacted in order to minimize the damaging effects of alcohol to our society. There are several ways drunk driving can be prevented, first is to designate a non-drinking driver, another is to call a taxi or a car-sharing service such as Grab. However, these methods have no way to prevent a drunk person from driving their own vehicle. Therefore, the purpose of this project is to develop an alcohol detection system with vehicle immobilization. The goal of the project is to develop a system based on a microcontroller, to monitor alcohol level in a person’s breath, to create a lock mechanism on a vehicle’s ignition and to evaluate the effectiveness of the project to prevention of drunk driving. The system utilizes an Arduino Uno as a microcontroller to control the input and output of the system and an alcohol sensor to measure the level of alcohol in a person’s breath, moreover, an OLED will display the value of the alcohol level gained from the alcohol sensor then a servo motor is used as an automatic lock on a vehicle’s ignition. This project is suitable as a method for recovering alcoholics or a person with a drunk driving offence to prevent themselves from commandeering a vehicle.
