| [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) |
Overview
PM2.5 Sensor Overview
- High SN by optimized optical design makes high-detectability of micro-particles.
- High-accurate conversion to mass-density value (μg/m3) by advanced algorithm.
- Built-in MCU, no need for external MCU.
- Unique internal fluid design has eliminated lens cleaning (*Fig. 1)
- Reduced stabilization time after starting (*Fig. 2)
Application
- Visualization of the air cleaning function of air purifiers and air-conditioners
- IAQ management for HEMS / BEMS
※HEMS:Home Energy Management System
BEMS:Building Energy Management System - Installation where maintenance cannot be provided
