Real-time Air Quality Index monitoring experiments using SDS011 sensors and raspberry pi

Abstract

This study aims to propose a real-time Air Quality Index (AQI) monitoring using SDS011 sensors and raspberry pi as a server to detect Particulate Matter (PM)2.5 and PM10. To calculate the AQI standard values, we refer to BMKG as the board responsible for regulating it. We collected data on the campus area close to the textile industry area in Purwakarta, West Java, Indonesia for 1440 minutes. From the experiments, the results of the AQI value for PM2.5 are between 66-110 or equivalent to 19.1 to 39.7 ug / m3, while for PM10 between 26-70 or equivalent to 23.1 to 43.9 μg / m3. This value shows the performance of the SDS011 sensor can work well. Furthermore, to be publicly accessible, the AQI and PM values are sent to the web every minute without having to refresh the web page. For further development, it is possible to make a low-cost portable monitoring device using SDS011 sensors and raspberry pi that can be placed in areas considered pollution-prone as a warning system when pollution has passed the permitted threshold.
