Description

This is the first CO2 sensor in the 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 (the voltage is lower than the threshold),  a digital signal (ON/OFF) will be released.

It has MG-811 sensor module which is highly sensitive to CO2 and less sensitive to alcohol and CO, low humidity & temperature dependency. 

Onboard heating circuit brings the best temperature for the sensor to function. Internal power boosting to 6V for heating sensor best performance. 

This sensor has an onboard conditioning circuit for amplifying output signal. 

This is an electrochemical Arduino-based CO2 sensor, it is suitable for qualitative analysis. DFRobot also developed other Infrared CO2 sensors, which are suitable for quantitative analysis.
