Abstract

The alcohol level detection system with ignition locking using Arduino will prioritize the convenience and satisfaction of users by giving something unique and never seen before. This project is primarily intended for usage on vehicle safety feature. As we know in Malaysia road accidents due to Driving Under Influence (DUI) has significantly increased in the past 10 years of time. Due to such careless behavior from the alcoholic person leads to loss of lives for the innocent. Malaysian Automotive Industry has posted a great challenge in order to reduce road accidents due to alcoholism. As a result, I started to look forward on this issue, where I came up with this project that was aimed to prevent road accidents due to Driving Under Influence (DUI) while also becomes a contribution to our Automotive Industries in Malaysia. By going through as much as literature reviews regarding Driving Under Influence (DUI), had gained more knowledge where it helps to develop the projects as well. Despite the current techniques to identify alcohol level in breath, I had selected the best materials and components to fabricate the circuit system for this project. By constructing the circuit design of this project an Arduino coding that connected to microcontroller which helps to run the system. Furthermore, the MQ3 sensor need a calibration method in order set the threshold limit where once the analog value hits the limit it automatically turn off the vehicle’s ignition system. Therefore, as an output, several data had been recorded from the system indicated the level of alcohol in breath. Thus, by implementing this project, in the near future we are able to aspect a gradual decreased on road accidents due to Driving Under Influence (DUI).
