V.Dust sensor PPD4NS/ PD42NS/ PPD42NJThe principle of
Particles and molecules produce light scattering when illuminated by light, and at the same time, they absorb part of the energy of the incident light. When a parallel

When a parallel monochromatic light is incident on the particle field to be measured, it is affected by scattering and absorption around the particles, and the light intensity will be attenuated. In this way,

The relative attenuation rate of the incident light passing through the concentration field to be measured can be obtained. The relative attenuation rate can basically linearly reflect the dust in the field to be measured.

The relative concentration. The intensity of light is proportional to the strength of the electrical signal after photoelectric conversion. By measuring the electrical signal, the relative attenuation rate can be obtained.

Attenuation rate.
