Abstract

Drunk driving is generally one of the most problematic things that most countries in the world will face. According to police report statistics, from 2018 to May 2020, there are about 70 accidents are caused by drunk driving in Malaysia, with more than 20 cases that were fatal. Thus, our country needs an efficient system to reduce the incidence of drunk driving. The project title is the development of an IoT-based car ignition interlock system with alcohol detector using microcontroller. The first objective of this project is to design and develop an IoT-based car ignition interlock system with alcohol detector using microcontroller. Then, the second objective is to analyze efficiency of an IoT-based car ignition interlock system with alcohol detector using microcontroller. In this project, a system will be implemented where if a drunk person wants to start their car, they must use the MQ3 Alcohol Sensor to check the alcohol level of the driver. The sensor will be connected to an ESP8266 Microcontroller. With some testing, experiments, and adjustment, if the driver is drunk, the system will lock the car ignition system and at the same time alert the driver’s emergency contact by sending them a message about the driver condition and the location of the driver to ease the driver's emergency contact located the driver. The results of the test will also be sent to an IoT software.
