LED Type PM2.5 Sensor

  • ◆ Mass-density numerical display (μg/m3) without using external MCU
  • ◆ Capable of visualizing IAQ (indoor air quality)


PM2.5 Sensor Overview

  1. High SN by optimized optical design makes high-detectability of micro-particles.
  2. High-accurate conversion to mass-density value (μg/m3) by advanced algorithm.
  3. Built-in MCU, no need for external MCU.


  • Air Purifier
  • Air Condiitioner
  • IAQ management for HEMS / BEMS
