arduino uno co2 sensor

Gravity: Analog CO2 Gas Sensor | Arduino Official Store

Great 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.
