Mg811/mg-811 Co2/carbon Dioxide Sensor Module For Arduino And Other Mcus For Sale
This sensor module has an MG-811 onboard as the sensor component.
There is an onboard signal conditioning circuit for amplifying output signal and an onboard 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.
