"Greenhouse Effect" melts the earth's ice core every minute and creates dangerous icebergs. By knowing the exact concentration of CO2 (carbon dioxide), we can do something to reduce CO2 and protect our planet. Here is the CO2 sensor developed by DFRobot.
This is the first CO2 sensor on the Arduino market. The output voltage of the module decreases with increasing concentration of CO2. The built-in potentiometer is used to adjust the voltage threshold. As long as the CO2 concentration is high enough (voltage is lower than the threshold), a digital signal (ON/OFF) is triggered. The sensor module MG-811 is highly CO2 sensitive and less sensitive to alcohol and CO, low humidity and temperature dependence.
The built-in heating circuit provides the best temperature for the sensor to function. Internal power increase to 6V for the heating sensor best performance.
This sensor has an integrated conditioning circuit to amplify the output signal.
In order to facilitate the use of this CO2 sensor, a Gravity Interface has been adapted that allows Plug&Play. The Arduino IO expansion shield is the best choice for this CO2 sensor that connects to your Arduino microcontroller.
This is an electrochemical CO2 sensor suitable for qualitative analysis. There are the other infrared CO2 sensors that could perform a quantitative analysis.
