Background
The working principle of the dust sensor is developed according to the light scattering principle, and particles and molecules can generate light scattering phenomenon under the irradiation of light, and simultaneously absorb part of the energy of the irradiation light. When a beam of parallel monochromatic light is incident to the measured particle field, the light intensity is attenuated under the influence of scattering and absorption around the particles. Therefore, the relative attenuation rate of the incident light passing through the concentration field to be measured can be obtained. And the relative attenuation rate is basically linear to reflect the relative concentration of the dust in the field to be measured. The intensity of the light intensity is in direct proportion to the intensity of the electric signal after photoelectric conversion, and the relative attenuation rate can be obtained by measuring the electric signal, so that the concentration of the dust in the field to be measured can be measured.
