3、ission distance, high cost and the difficulty to maintain, the atmosphere PM2.5 monitoring system based on ZigBee technology is designed. The system combines the advantages of ZigBees low cost, low power consumption, high reliability and GPRS/Internets capability of remote transmission of data. Furt
4、hermore, it adopts TIs Z-Stack protocol stack, and selects CC2530 chip and TIs MSP430 microcontroller as the core, which establishes the air pollution monitoring network that is helpful for the early prediction of major air pollution disasters. 1Introduction PM2.5 refers to particles that can be sus
5、pended in the air for a long time in the air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. Due to the small particle size, large area, strong activity, easiness to carry toxic and harmful substances (such as heavy metals, microorganisms, etc.), PM2.5 has a great impact o
6、n human health and air environment 1. In addition, the continued accumulation of PM2.5 concentration easily lead to a wide range of fog and haze weather. In China, the monitoring of PM2.5 is lagging behind, and only a few areas of the country have monitored PM2.5 before the national release of the latest ambient air quality standards. Due to the large variety of concentration of PM2.5 in residential areas, commercial areas and local production-intensive areas, it is not possible to rely on
