Project  background

At present, the increasingly complex air pollution situation is presenting new challenges to the traditional methods of monitoring air pollution sources. The currently implemented ambient air national control point monitoring system has a limited number of monitoring points and a high cost. The method of replacing points with points leads to insufficient timeliness, fails to achieve the goal of fine management and control, and fails to achieve analysis of the spatiotemporal dynamic trends in the monitoring system. , In-depth exploration of pollution reduction assessment, pollution source tracking, environmental early warning and forecasting capabilities.

Combined with the requirements of the General Office of the State Council on the construction of an ecological environment monitoring network, Yiyuntian has developed a set of low-cost, multi-parameter integrated compact micro-environmental air monitoring system that can realize high-density grid layout with rich experience in the field of gas detection. , And gridded monitoring system can fully cover the monitoring area, and achieve high spatial and temporal resolution of atmospheric pollution monitoring, combined with the application of information big data, to achieve pollution source tracking, early warning and other functions, for environmental pollution prevention and control More timely and effective decision support.

TH2000-W miniature ambient air monitoring system is mainly composed of gaseous pollutant detection module, particulate matter detection module, meteorological parameter sensor, wireless communication module, power supply and power management unit, etc. The monitoring factors include VOCs, SO2, NO2, CO, O3, PM10 , PM2.5, temperature, humidity, wind speed, wind direction.
