Abstract

Indoor air quality and human health have proven to be related, but for home environment air quality detection system equipment accuracy is not high problem. This paper designs an air quality detection system that effectively handles the information of indoor air pollution. The microcontroller unit (MCU) STC12C5A was taken as the core to realize the detection and display of particulate matter (PM) 2.5 concentration, temperature, and humidity. Compared with the measurements by standard instruments, our system was proved effective through tests: the relative error of PM2.5 concentration was smaller than 3μg/m3; the temperature error was within 1℃; the humidity error was below 5% relative humidity (RH). This research provides an effective way to detect indoor air quality. The results of this paper are suitable for home environment and have a good application prospect.
