CO2 Sensor MG811 (Arduino compatible) Botnroll

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.

: SainSmart MG811 Gas Sensor Module for Arduino ...

Later I bought a AD power converter and a couple of separable power jack connectors so that I split the 6V supply into the Arduino and the MG811 sensor. Another problem I had was that the signal output is quite low, only about 330 mV at normal atmospheric levels. Zero CO2 concentration would produce an output voltage of about 280 mV.

[MG811] CO2 sensor problems Sensors Arduino Forum

May 06, 2021· Hello everyone. I''m working on a project that has to have a co2 sensor detect average amounts of atmospheric co2. It uses many other sensors, including gas sensors, and I have not had any real problems connecting any of them until I got to the MG811. I have been troubleshooting this for days now, the main problem resulting from lack of documentation and detailed guides.
