Principle Introduction

MEWOI-MIX2111D-EXP Combustible Gas Detection Module adopts semiconductor gas sensor, featuring high sensitivity, small size and long life. It also adopts digital UART interface output with user calibration function. The sensor has high sensitivity to combustible gases such as alkanes, alcohol, hydrogen, carbon monoxide and natural gas. The module was already aged, debugged and calibrated, it has good consistency and high sensitivity.
This product adopts array combination or single module, installed in the vicinity of combustible gas pipelines, valves, filling equipment etc., quantitatively monitors the concentration of combustible gas, organic vapor and other hazardous chemicals in the environment, with the background alarm system. It can effectively provide early warning of potential hazards.


* High sensitivity to combustible gas
