How to use MG811 - Sensors - Arduino Forum

06/05/2021· 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).
