Emission Gas Detector (EGD) for Detecting Vehicle Exhaust Based on Combined Gas Sensors

Abstract

In the modern era, combination of several sensor types to determine the vehicle exhaust content is needed. Dangerous and toxic vehicle exhaust, such as HC, CO, CO2 and NO, needs to be controlled to reduce air pollution level. The vehicle exhaust content level can be measured by applying a combination of several sensors. In this research, a tool to detect vehicle combustion system condition based on vehicle exhaust content level has been designed. The tool combines several sensors, they are: TGS22001 sensor, TGS2602 sensor and MG811 sensor. Bluetooth HC-05 technology is also used to support Android-based information system. The combination of these technologies makes all of gas detection result can be known in real time and updated via smartphone. Arduino UNO R3 module is used to control all systems (gas- sensor-ADC-interface-Bluetooth-display). The results of combustion level test conducted on 15 motorcycles are: 8 motorcycles are bad, 4 motorcycles are medium and 3 others are good.
