In recent years, the problem of environmental pollution has been plagued people's lives, especially the problem of air pollution is not only a serious threat to human life and health, but also caused ecological damage. With the worsening of urban air pollution, urban management departments will choose to deploy air environment monitoring terminals to realize grid management and online monitoring in order to collect air quality data in various regions in real time.

So, what is grid monitoring? Air quality grid monitoring system is a point, line, surface layout, the city air monitoring as an integrated realization of air quality data online monitoring, collection system. It is mainly for the environmental management department, aiming to help and solve the problem of environmental air quality monitoring in the region, provide accurate and real-time monitoring of air pollution, evaluation, analysis to help users grasp the environmental air quality in the region, find the pollution characteristics, and provide technical support for the prevention of air pollution.

The air quality grid monitoring system uses small and intelligent air quality monitoring micro-stations to build a grid monitoring network, including: fixed point monitoring of air quality micro-stations, vehicle-mounted mobile monitoring of air quality micro-stations, air quality unmanned aerial vehicle monitoring, etc., and uses Internet of Things technology to obtain data of each monitoring point in real time, based onGISTechnology presents an air quality map. Through the humanized operation interface (PCend, mobile phone end), analyze and judge the displayed monitoring data, and provide air quality early warning, analysis of major pollutant sources, source traceability, air quality reporting and other services.

The significance of the air quality grid monitoring system is great. It can not only provide the management department with the monitoring, evaluation and analysis of the ambient air quality in the region, but also timely discover the characteristics of pollutants, provide the whole process tracking function of pollution event discovery, confirmation, disposal and summary, and can be used by mobile phone.APP, WeChat public number, network and other information multimedia channels to issue early warning in a timely manner, to achieve "early detection, early warning, early processing".

For the grid monitoring of ambient air quality, Shenzhen has a complete set of sensor solutions.B4Sensors are electrochemical sensors that focus on monitoring air pollution and air quality, and can be applied to hardware facilities in air quality grid monitoring, such as fixed detection stations, mobile vehicles, drones, etc;B4The sensor can effectively monitor some toxic gases that may exist in the air, suchCO,O3,NO2,SO2and so on;

ForVOCswe recommend usePID-AHPhotoionization detector, it is a small range, high resolution for detectionVOCThe gas sensor has a range1ppb-50ppm，PIDBecause of itsVOCThe high sensitivity of hazardous substances has become an indispensable tool for early hazard alarm and leak monitoring.

For the detection of the number and size of micro-particles in cities, the scheme we provide is alphaOPCSensors. As people gradually realizedPM2.5Impact on human health and the environment, UKAlpahsensedeveloped and launchedPM2.5SensorOPC-R1withOPC-N3;It uses the principle of light scattering and particle counting technology to accurately detect the number of micro-particles in the surrounding environment, and the micro-environment improvement provides reference data for use.
