Which kind of dust concentration sensor has high measurement accuracy?

At present, most environmental monitoring instruments belong to pollution source monitoring, that is, where there is pollution, there is monitoring. Construction sites will produce dust because of large-scale operations, which is the main source of urban dust pollution. Installing a dust monitoring system on the construction site can effectively improve the dust environment. When the dust produced by the operation reaches a certain concentration, certain dust reduction measures will be taken to reduce dust pollution.

CW-76S construction site dust sensor (dust detector) is a high-tech product which integrates aerodynamics, digital signal processing and photoelectricity independently developed by Shenzhen Sainawei. It is mainly used to detect the dust mass concentration (PM value) in the atmosphere, and is suitable for construction sites, urban grid monitoring, mobile monitoring and other fields and occasions. It is the core module of air quality detection system. Its main features are as follows:

Accurate data: laser principle detection, industrial photoelectric induction; High resolution: ≥0.3um particle size, 0.00 1mg/m? ;

Detect PM2.5, PM 10, TSP；;

Stable performance: it can adapt to the composition of dust substances in different atmospheric environments and adjust the parameter coefficient independently;

Data transmission: 485(Modbus standard protocol) or RS232, UART output; Provide switch output, which can be connected with outdoor acousto-optic alarm equipment.

Intelligent monitoring: real-time monitoring of sensor indicators, and timely feedback to users when abnormal conditions occur;
