Principle Introduction
| MEWOI-MIX2111S 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 * Level Display * Long use life |
Application
* Air purifier * HAVC refrigeration * Indoor air quality monitoring * Intelligent integrated ceiling |
