Background
The fine particulate matter is also called fine particles, PM 2.5. Fine particles refer to particles having an aerodynamic equivalent diameter of 2.5 microns or less in ambient air. It can be suspended in air for a long time, and the higher the content concentration in the air, the more serious the air pollution is. Although PM2.5 is only a component of earth's atmospheric composition in small amounts, it has a significant effect on air quality and visibility, among other things. Compared with the thicker atmospheric particulate matters, the PM2.5 has small particle size, large area, strong activity, easy attachment of toxic and harmful substances (such as heavy metals, microorganisms and the like), long retention time in the atmosphere and long conveying distance, thereby having larger influence on human health and atmospheric environmental quality.
The current methods for measuring PM2.5 mainly comprise the following 5 methods: infrared and turbidity methods, laser and particle counting methods, Beta ray methods, micro-oscillation balance methods, gravimetric methods. Because the performance of the sensor for measuring PM2.5 by an infrared method is poor, and the principles of the Beta-ray method, the micro-oscillation balance method and the gravimetric method are difficult to apply and have high price, PM2.5 sensors for measuring the concentration of PM2.5 by adopting a laser scattering principle are more available on the market. Because this kind of sensor is laser scattering, to the dust immunity of electrostatic absorption, but when the device was in service, need let in the air to the device, the air is when passing through the device, and partial dust and particulate matter can remain inside the device in the air, and after long-term use, these impurity probably blocked the sensor, and then made the detection function of device decline.
