Remarks:
ZPH02 dust sensor uses power resistors to heat the air, the hot air promotes the ambient gas
(PM2.5) into the detection of light path, so as to detect. The optical structure determines the
installation of the sensor has certain specification requirements, otherwise it will lead to abnormal
detection data.
