Laser Type PM Sensor

◆Realize “Visualization” of IAQ (indoor air quality) by indicating mass-density (μg/m3)

◆Laser-type sensor makes better accuracy and higher stability comparing LED-type one


Laser Type PM Sensor Overview

  1. Smaller size (37 x 37 x 12mm)
  2. Better accuracy (±10%) from low to high concentrations
  3. Longer life-time by optimizing electrical/SW control
  4. Auto calibration function
  5. Less dust-accumulation structure for minimizing electrical tracking


  • For home appliance products and/or air quality monitors which need more accuracy & further advantages to the competitor's
