: SainSmart MG811 Gas Sensor Module for Arduino ...

Later I bought a A-D 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.

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).
