Yes, i found some results, but , i don't know how calibrate the read with amonio.
i found videos for the CO2 in youtube.

thank you so much.

The basis of ANY calibration is a standard. When we had a nitrogen generator system, the nitrogen calibration was done using a standard oxygen concentration gas in canisters. You will have to have a known concentration of ammonia gas to see what your sensor reads and use that value as a base concentration.
Do you have a known ammonia gas concentration to work with?
