CO2 Sensor (Arduino compatible)

Description

"Greenhouse Effect" is melting the iceberg every minute,. By knowing the exact concentration of CO2, we can do something to reduce the CO2 and to protect our earth. For that reason, a High quality CO2 sensor is designed by DFRobot eningeer . This is the first CO2 sensor in opensource hardware 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. Once the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
