Study Of Atmospheric PM2.5Monitoring System Based On ZigBee

The Internet of Things introduces new ideas, new technologies and new methods to atmospheric monitoring system. The embedded sensors to atmospheric monitoring system of PM2.5particles in the atmosphere, the perception of size and concentration of toxic gases and other information. The promotion of network supervision platform will existing decentralized,independent, single for the integrated network supervision platform system, open, pluralistic.Wireless sensor network is a key technology development of the IOT, it is the rise of technology in recent years, with its distribution network features convenient, low-power, low price, has attracted wide attention. Will be applied on atmospheric PM2.5monitoring is wired to the existing good supplement, especially in some blind spots with wired monitoring network cannot be monitored, and the wiring cannot place. Wireless monitoring and wired monitoring combined with integrity will improve the monitoring system greatly. This topic will be the application of ZigBee technology in atmospheric PM2.5monitoring system, will be very good to improve the deficiency of traditional instant communication, through the establishment of atmospheric pollution monitoring network system, is of great help to predict sudden major disasters of atmospheric pollution events.This paper is based on the wireless communication protocol ZigBee,using TI’s Z-Stack protocol stack, using CC2530chip as the core,implements a selfnetwork PM2.5wireless monitoring system of organization, low cost.System uses a modular set, consists of three parts, specifically for the sensing and control module, a wireless network coordinator module and embedded gateway. Sensing and control module as the terminal nodes of the network, place a suitable position, the monitoring of environmental information,the datamessage to the coordinator. The coordinator establishes the wireless sensor network, security of networknormal communication, transmission of data information. The embedded gateway acts as a management center, to enable managersto carry out data transmission and control of the whole wireless sensor network. Through the field test and the same DustTrak II compared with foreignequipment, proves that the system measurement accuracy, wide application prospect.
