The dust sensor for fresh air system uses a laser diode as the light source to illuminate the sampling air boosted by the blower. When the small particles in the air enter the illuminated area, the laser beam is scattered. A photodetector placed in the specified positon receives the scattered light and turns it into current signal which is then amplified and processed to indicate the concentration of particles. The final output is serial digital signal.
- Good consistency
- High accuracy
Applied in environmental appliances，air purifier, air quality detector and other equipment.
