Gas Sensor MG-811 CO2 Carbon Dioxide

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. The output voltage of the module falls as the concentration of the CO2 increases.

Applications

Air quality control, ferment process, in-door air monitoring application.
