Abstract
Indoor air quality is a problem that needs attention because it will affect human health. To maintain indoor air quality, it is necessary to regularly monitor several parameters that can affect air quality. Along with the development of sensor and monitoring technology based on IoT (Internet of Things) which helps a lot in designing monitoring devices automatically and periodically. This supports us to conduct research in designing a device that can periodically monitor indoor air quality conditions. In this study we designed an air quality monitoring system using the ESP32 as a controller and several sensors to measure air quality. The result is a system that can monitor temperature and humidity, dust particles and polluting gases (H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> S, NH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> , CO, NO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> , and SO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ).
