DFRobot Gravity MG811 Analog CO2 Gas Sensor linear Key details include Frequency Range:Add Reliable Gas Carbon Dioxide CO2 Analog Sensor Gravity Sensing to Your Next Build Gas CO2 Analog Sensor Gravity. "Greenhouse Effect" is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2, we can do something to reduce the CO2 and to protect our Earth. For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of
