Abstract

Exhaust gas from the combustion of fuel oil in motors contains pollutants such as CO, HC, CO2 and other gas particles. Measuring emission levels in motor vehicles in addition to using visuals by looking at the color and smell coming out of the vehicle exhaust must also be measured using a measuring instrument called an automotive emission analyzer which is usually found in agencies or official workshops that are tasked with testing emission levels in motor vehicles. The high cost of testing vehicle emissions and the limitations of existing measuring instruments require a microcontroller-based tool to measure CO, HC, and CO2 exhaust emissions. This tool can detect and display vehicle exhaust gas results in the form of CO, HC, and CO2 based on data from the sensors used. This tool uses MQ-7 and MQ-135 gas sensors as the main components to detect CO, HC and CO2 gases in vehicle exhaust gas. ESP32 as a microcontroller to process data from sensors and display concentrations on a 20x4 LCD screen and the Blynk application. To provide information on the gas obtained, there is a notification from the Blynk application which will later provide a notification for one minute. To ensure the accuracy of CO, HC, and CO2 gas measurements optimally, it is necessary to implement a sensor comparison technique with tools in industry or agencies. In the calibration and field testing in the reading of the MQ-7 and MQ135 sensors, the error presentation is not more than 5%. In addition, the tool is equipped with a Buzzer and LED lights. The Buzzer and LED lights work when the gas concentration exceeds 4.5% for CO, 1400 ppm for HC and 20% for CO2. In this system, it provides a bad condition for motor vehicle emissions indicated by CO, HC, CO2 gases. The test results show that the developed tool is able to detect CO, HC, CO2 gases effectively. The development of this tool is expected to be applied to the automotive industry, and the environment for human health.
