Hi @fornoalpigraie, I am sorry to read that you are facing issues with the CO/NO2 sensor readings. Please, disconnect the shield from the base board and connect it again to check if any pin contact is not working properly. If this does not work, please, let us know. All the best.


thank you very much,
I will check on sunday when I will be there
best regards


Here I am again.

I disconnected the base board and restarted the kit, but the behaviour is the same: no more data for NO2 after two days, CO data seems ok

could you please help me?

best regards,
