Abstract

In recent years, due to excessive levels of indoor air pollutants in teaching, there has been an increase in the number of cases of physical illness among primary and secondary school students, thus triggering key national concerns. Traditional air purification devices mainly purify air by means of filtration, they are single-functional and work independently, which makes it difficult to manage centrally. In order to protect students' physical and mental health and improve indoor air quality, a microcontroller-based intelligent control system for space disinfection is designed. The system adopts GD32 microcontroller as the main controller to realize filtration, purification and detection functions, and the air purification equipment connects to the IoT platform through 4G CAT1 chip and MQTT protocol to realize remote detection and control. The test shows that the system is reliable and stable in operation and simple in operation, the system has multi-sensor detection function and can accurately detect ozone, ammonia, formaldehyde, PM2.5, TVOC, carbon dioxide, temperature and humidity in indoor air. Therefore, the system can effectively improve indoor air quality, it solves the problem that the current equipment on the market works alone and has a single function and has a high practical use value.
