Abstract—This study focuses on the purification and monitoring of indoor air pollution aided with UV light radiation intended for laboratory and lecture rooms in Bataan Peninsula State University. The developed air recirculation prototype utilizes Arduino integrated development environment (IDE) software with two air quality sensors namely, BME680 and PMS5003, which send signals to relay to control the purification and monitoring operations. As a monitoring device, the prototype is capable of displaying real time air quality measurements as well as pollutant concentrations. The measured data control the purification process which activates only at acceptable range of indoor air quality (IAQ) allowing the prototype to conserve energy. Two approaches on monitoring accuracy were done with respect to the distance of prototype sensors to the air quality tester. While for the effectiveness of purification process, a five-minute recalibration speed on smoke tests were conducted. This study aimed to help in reducing the intake of harmful air on the human body that causes cardiovascular diseases, respiratory problems and even viruses, more particularly in indoor environments like laboratory and lecture rooms.
