Microcontroller-based air quality monitoring design using mamdani fuzzy method

<span>Hazardous gases such as carbon monoxide (CO) and sulfur dioxide (SO<sub>2</sub>) not only emerge in the outdoor environment but also inside house or factory which will endanger occupants workers. The detection devices are mainly found on public roads since detected gas mostly consists of CO SO<sub>2</sub>. design air quality monitoring is proposed with applied sensors TGS2201 MQ136. device, when activated, detect components room. results be displayed value concentration quality. If exceeds specified threshold, fan act to neutralize contained air. Fuzzy logic membership function using Sugeno model. test box maximum pollution 80 ppm according motor vehicle gas, out at a road 51 ppm. Each method has differences 29 ppm.</span>
