The sensor is based on the particle concentration analysis technology of Mie scattering theory. A laser light source illuminates a particle as it is pulled through the detection chamber. The particles are scattering when passing through the laser beam. The information processing circuit converts the light intensity signal of the scattered light via the photoelectric sensor into a voltage pulse signal, which is preamplified, converted by AD into
