Abstract
With the development of industrial technology, China's smog weather is frequent, affecting air quality and human health. It is important to monitor indoor air quality in real time and make timely processing. This paper designs an air quality monitoring system based on ZigBee wireless sensor network. The system consists of multiple terminal modules, a coordinator module, a control module, and a monitoring center. The terminal module collects data using a variety of sensors and sends them to the monitoring center through the GPRS. Once the air quality index exceeds the set threshold, the user is promptly alerted and the corresponding air purification process is performed. The system is simple and convenient, the monitoring result is accurate, the real-time performance is high, and the application is extensive.
