[discontinued] MG-811 Gas CO2 Carbon Dioxide Sensor

SKU: 101-60-211
Ups, 0 verfügbar.


This sensor module has an MG-811 on-board as the sensor component. There is an on-board signal conditioning circuit for amplifying output signal and an on-board heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring application. The output voltage of the module falls as the concentration of the CO2 increases.

  • Size:32mm X22mm X27mm (LxWxH)IC: LM393?MG811
