In recent years, the problem of environmental pollution has been perplexing people's lives, especially the problem of air pollution is becoming more and more serious, which seriously threatens people's life and health. presented in the state“double carbon”Under the background, all over the country have embarked on the road of accurate control of haze. while the atmospheric networkBecause of its accuracy and science, the chemical monitoring system can effectively improve the work efficiency of haze control, and can provide data and technology advantages for environmental supervision, it has become the new mainstream of accurate haze control, and is also loved by some places.

1.     What is Atmospheric Networked Monitoring System

The grid integrated monitoring system of atmospheric environment is mainly for environmental management departments (such as city, county government and environmental protection management agencies), aiming to help solve the problem of environmental air quality monitoring in the region, provide accurate and real-time monitoring, evaluation and analysis of air pollution, help users grasp the environmental air quality status in the region, find the pollution characteristics, and provide technical support for the prevention and control of air pollution.

The atmospheric grid environmental monitoring system consists of three modules: information collection, data display and analysis, and application platform. It adopts the grid layout of points, lines, and surfaces to realize multi-dimensional integrated monitoring and management of the urban regional environment. In addition to monitoring regular meteorological factors such as air temperature and humidity, wind speed, wind direction, and atmospheric pressure, it also mainly monitors particulate matter.PM2.5、PM10And the real-time concentration of nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone and other gases.

2.     Introduction of the sensor

The British alphansense sensors acting in Shenzhen have specially introduced ambient air quality sensors for the field of atmospheric monitoring, including toxic gas sensors A4/B4 series, PM2.5 and PM10 particulate matter detectors OPC series, which are very suitable for application in atmospheric network environment systems.

Alphasense的B4The fourth electrode of the series of electrochemical sensors is used as an auxiliary electrode to compensate the zero-point current, making it have the characteristics of high signal level, low zero-point current, resolution can be as low as less than 10 ppb, fast response, short reaction time, Anti-interference, wide working range and other obvious advantages, can be applied to some fixed monitoring stations in urban streets.

Alpha pioneered a series of optical particle sensors based on the principle of light scattering(OPCs), This series has been continuously developing, providing customers with the best quality and lower cost sensors on the market. At present, our products:OPC-N3andOPC-R2。
