Dust sensor - you don't know what the dust sensor is for

Update: 2019-09-02 14:29 Source: LUFTMY Reading: ↻ News
 

Dust sensors are mainly used to detect the concentration of dust in the environment. At present, people have higher and higher requirements on the living, working and living environment, and the harm of productive dust to human body is increasingly prominent. Its main working principles are light absorption, light scattering, beta rays, microcomputer laser and ac electrostatic induction principle; It is mainly applied to various research institutions, meteorology, public health, industrial labor health engineering, air pollution research, etc.

Dust sensors are widely used in the center for disease control, mining, metallurgy, chemical manufacturing, health supervision, environmental monitoring and so on. There are five kinds of rapid detection methods: light scattering method, beta ray method and microgravimetric balance method, electrostatic induction method and piezoelectric balance method.

Light scattering method dust sensor foreign, domestic manufacturers more. Also divides the ordinary light scattering, and the laser light scattering method. Because of its good repeatability and stability, laser light scattering method has completely replaced ordinary light scattering method in Europe, America and Japan. If choose good manufacturer, can achieve high cost performance. The quality of sensors varies greatly in China, so we should choose the manufacturer with guaranteed quality.
