MG811 Carbon Dioxide Sensor soldering Power Out: 5V-800mAThis sensor module has an MG 811 ( MG 811 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
