Principle Introduction:

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.


Lower power consumption

High sensitivity, long life

Calibrated before shipment

Auto-preheating (10sec.-3min.)

Faulty auto-diagnosis
