Principle Introduction
| Xtester-MIX2111D-LEL 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 VOCs such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol, cigarette smoke, perfume etc., methane and propane. The module was already aged, debugged and calibrated, it has good consistency and high sensitivity. |
