MG811 CARBON DIOXIDE CO2 GAS SENSOR MODULE

OverviewThis sensor module has an MG-811 gas sensor on-board and circuitry to enable it to work out of the box. This MG811 sensor module is a little bit special because it requires 6VDC to function properly. There is an onboard signal conditioning circuit for amplifying the 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, and in-door air monitoring application. The output voltage of the module falls as the concentration of CO2 increases.
