Is there any code to arduino in order to read from the  MG811 CO2 Sensor?


Google will no doubt tell you if there is...


I didn't find anything on google.


Well there probably isn't then  :P

Everywhere I know of that would have code like that would show up on google.


at the end do you know now the cod for co2 sensor?

Q1: Do you have a link to a datasheet?
Q2: Do you have experience with Arduino projects? or uProc in general?
Q3: what is your goal you want to achieve?
Q4: The supplier of the device, does it have examples on his website? (assuming she has one)

Seems it need some signal boosting to provide a voltage Arduino will handle properly. Furthermore You need a quite stable 6Volt for the heating unit.

you can mail the supplier
