[MG811] CO2 sensor problems Sensors Arduino Forum

06/05/2021· 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.
