An air quality monitoring station is a facility specifically designed for real-time monitoring and recording of various pollutant concentrations and meteorological parameters in the air. It can accurately measure meteorological parameters such as PM2.5, PM10, sulfur dioxide, nitrogen dioxide, ozone, and carbon monoxide, providing data for environmental departments

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