Principle Introduction
| MEWOI-MIX2111 air-quality module adopts semiconductor gas sensor. The module has good sensitivity to volatile organic gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol and smoke of cigarette, essence &etc. The module has been aging, debugged, adjusted and calibrated. So it has good consistency and high sensitivity. |
Features
| Lower power consumption High sensitivity, long life Calibrated before shipment Auto-preheating (10sec.-3min.) Faulty auto-diagnosis |
Application
| Air purifier , Automatic fans , HAVC refrigeration , Indoor air quality monitoring , Intelligent integrated ceiling |
