Air quality is constantly deteriorating with the rapid economic development in the 21st century, and air pollution has changed from the coal-burning pollution to the combined pollution caused by coal-burning, vehicle exhaust emissions and industrial emissions. Environmental air quality has been the key concern of people, in order to protecting people healthy, and it's greatly necessary to build a complete environmental monitoring system outdoors. In fact, most of the current environmental monitoring system at present has some problems such as single or partial utility, poor real-time response, wire communication needed and lag time response, et al. In this research, we integrated all of the monitoring functions such like PM2.5, CO, NO2, SO2, noise, temperature and humidity which are satisfied with Chinese environmental air quality standard (GB3095-2012) into one whole system, and it makes this monitoring system very convenient and well rounded to use. Especially, we combined ZigBee and 5G technology together, and it shows that this idea exhibit the merits of these two technology to solve the long distant wireless communication and the real time response problems which makes sure that all of the monitoring data can be transmitted to the information center timely and accurately. We used CC2530 chip for the short distance wireless transmission, and the ZigBee wireless sensor network was established by using z-tack protocol stack made by Texas Instruments (TI) Company to achieve short distance acquisition and transmission. Moreover, the a kind of field programmable gate array (FPGA) is adopted to realize long-distance information transmission by heterogeneous network with using EP4CE10F17C8 chip to convert ZigBee data frames into 5G data. The results show that this environmental air quality monitoring system can accurately realize the seven parameters monitoring demand according to the standard of GB3095-2012, and the monitoring data can be obtained by real time, wireless and long distant communication which is a kind of perfect choice for the wide area environmental air quality monitoring work.
