Beschreibung
Zusammenfassung:	A dual-passage air quality detection device includes a housing, an air quality detection module, a fan, and a main control PCB (printed circuit board). The air quality detection module includes two passages, two laser modules and two photodiodes therein. The fan includes two fans. One of the passages is communicated with the inside of the vehicle, and the other of the passages is communicated with the outside of the vehicle to form two independent air passages for detection. Each of the passages corresponds to one fan for independent sampling, not affecting each other.
