Principle Introduction

MEWOI-MIX2111D adopts semiconductor gas sensor, featuring high sensitivity, small size and long life. It also adopts digital UART interface output with user calibration function. 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. 


* High sensitivity to methane

* Long life, small size

* Good stabilit


* Portable gas detector

* Fixed gas alarm
