Abstract

The purpose of this study is to create an Internet of Things (IoT)-based air quality monitoring system that can be used in rooms to improve comfort and check air quality.  The NodeMCU microcontroller ESP8266 equipped with a DHT11 sensor for temperature and humidity as well as an MQ-135 air quality sensor.  The Blynk app and OLED LCD display display display environmental data in real-time, which makes it easy to monitor without having to be on site.  The design is carried out through research and development (R&D) methods. This process includes the stages of identifying needs, designing, implementing, and testing the system in the field.  The results of HasiI testing showed that the system was able to provide accurate and stable data even though the temperature and humidity deviations were still within tolerance limits.  It is hoped that this system can help maintain air circulation in the room and increase awareness of the importance of air quality in the surrounding environment.
