1.Introduction toair quality monitoring stations

Air quality monitoring station, also known as air quality detector, atmospheric environment air quality monitoring station, air quality monitoring station is mainly used for urban air quality monitoring, air quality grid monitoring, urban roads, airports, ports, railways, tunnels, construction sites Atmospheric monitoring, particulate matter and pollution source emission monitoring, and environmental quality assessment.

The WX-WZ01 micro ambient air quality monitoring system consists of various environmental sensors, data collection main control, wireless communication equipment, power supply equipment, and software platform.It can be used to measure various types of ambient air data such as PM2.5, PM10, CO, SO2, NO2, O3, TVOC, etc.The system adopts a modular design, which can flexibly add or reduce corresponding modules and sensors to various environmental elements according to different regional environmental conditions, and can be combined in any way to meet various user needs conveniently and quickly.Data is uploaded to the cloud management platform via wireless/GPRS, and big data intelligent dynamic analysis is used to provide timely alarms and precise source locking to strengthen the supervision system.
