What is the difference between that 2 versions of the sensor board : v1.1 and v1.1c ?
I have the 2 versions and it seems the latest version is more accurate.
Is t right or my v1.1 sesnor board is out of order ?
There is no change that affects the accuracy of the board between v1.1 and 1.1c hardware versions. The only differences are some optimizations in the routing of the board, a more robust usb.
So i think my Ambent board v1.1 is not working fine: relative humidity, NO2 and CO values are incorrect.
How to get only the Ambient board ?
