Application of PM2.5 sensor in air pollution monitoring

Update: 2020-08-06 14:54 Source: LUFTMY Reading: ↻ News
 

In recent years, China's ecological environment construction is becoming more refined and intelligent by means of sensor and big data technology.At present, in China, with the extensive use of sensors, testers are able to collect and even collect data at a low cost. The greatly increased amount of data will enable people to quickly make more accurate decisions and countermeasures in various situations.

Application of PM2.5 sensor in air pollution monitoring

At present, many local ecological and environmental departments are using the Internet, big data, artificial intelligence and other new technologies to explore models of environmental governance, innovate environmental supervision measures, and implement fine management and precise pollution control.For example, for severe air pollution, the former Ministry of Environmental Protection began to explore the establishment of air pollution hotspots grid supervision methods and systems.Satellite remote sensing and big data analysis technologies will be used to screen air pollution "hot spot grids" to assist law enforcement inspection, so as to improve the accuracy of environmental regulation.

The model through the city and the surrounding land is divided into a grid, integrated satellite remote sensing and ground air quality monitoring, meteorology, atmospheric pollution sources, such as data analysis, use of big data inversion technique to draw each grid of PM2.5 concentrations, and combined with the conditions of atmospheric pollution sources distribution around the screen out highest PM2.5 concentrations, the heaviest grid as a hotspot in grid atmospheric pollution emissions, in order to improve the level of scientific and accurate for the control of air pollution.

At present, the air pollution hot spot grid monitoring system adopts the air automatic monitoring micro-station, which adopts the multi-sensor information fusion technology.A variety of gas environment monitoring sensors, such as PM2.5 sensors and dust particle monitoring sensors, are installed in meteorological monitoring stations to achieve comprehensive and real-time monitoring of the atmospheric microenvironment.

PM2.5 sensor selection recommendation:

LD13C laser PM2.5 sensor is a high-precision particulate matter concentration sensor based on the MIE scattering theory of laser. It can continuously collect and calculate the number of suspended particles with different particle sizes in the air per unit volume, namely the concentration distribution of particulate matter, which can then be converted into the mass concentration and output in the form of a universal digital interface.The sensor can be embedded into various instruments or environmental improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data.
