Gravity: Analog CO2 Gas Sensor (MG-811 Sensor) Sound&Audio amongst othersGreat and powerful sensor for everyone that wants to know the exact concentration of CO2(Carbon Dioxide) in the air. This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON OFF) will be
