[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.

How to use MG811 - Sensors - Arduino Forum

May 06, 2021· Hi. I got the sensor MG811 that senses carbon dioxide, you can see an image of the sensor here I googled to use that sensor properly but i have doubts about the wiring with arduino and the proper way to calibrating. So, i got think i can got the data from AOUT pin, but i really don't know if i can use the 5V pin from arduino to connect in vdd or i need another source (around 12V).
