The air quality module adopts advanced semiconductor gas sensor. The sensor has extremely high sensitivity to organic volatile gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol, cigarette smoke, and essence. The module has been aged, debugged, calibrated and calibrated, and has good consistency and high sensitivity.
Features
* Extremely high sensitivity, excellent long-term stability
* Low power consumption, long life, high cost performance
* The factory has been calibrated and calibrated, (10S-3Min) automatic preheating judgment
Application
* Air purifier, fresh air ventilation system
* Intelligent integrated ceiling, air quality monitor
* Ventilation fan, air conditioner
