Abstract

This project aims to apply the warning system to prevent accidents which involving vehicles such as cars and trucks when the driver was drunk by using the detection of breath alcohol detector’s concept or, more commonly known as a breathalyzer system that can monitor the person's blood alcohol concentration. This product can detect the presence of alcohol molecule in the breath sample and displays the results by referring to the alcohol concentration are detected from the driver once the driver want to start to drive the vehicles. In this project, the design of this project includes the development of hardware and software as the device modules. Hardware part includes of the sensor circuit, the PIC Microcontroller circuit, LED circuits and Buzzer as the alarm circuits. Software part will covers coding programming in the PIC microcontroller by using PIC C programming. During testing, breath alcohol detector can detect the presence of alcohol from the breath sample from drunken driver. Breath sample will analyzed and displayed in units of the Blood Alcohol Concentration (BAC). Breath samples were analyzed and presented in the unit value of Blood Alcohol Concentration (BAC). Based on the values that have been detected alcohol breath, this system will operate and will give warnings to the drunken drivers who are in drunken condition to not continue driving the vehicles via alarm from buzzer and LED will show their BAC.
