(New Product) LED type PM2.5 sensor (SN-GCJA6)

[New Function] ◆ Substantial maintenance reduction by eliminating lens cleaning
[Improvement] ◆ Increased accuracy (*from existing LED type sensor (SN-GCHA1))
◆ 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.
  4. Unique internal fluid design has eliminated lens cleaning (*Fig. 1)
  5. Reduced stabilization time after starting (*Fig. 2)


  • Visualization of the air cleaning function of air purifiers and air-conditioners
  • IAQ management for HEMS / BEMS
    ※HEMS:Home Energy Management System
