quot;Greenhouse Effect" is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2, we can do somehing 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 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 (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
