We have collected a lot of data now and I think we are becoming comfortable that devices are providing reliable readings. Do you agree?
We have not though carried out a formal validation in of devices in the field and I think we should consider doing this. A validation exercise would need 2 or 3 co-located devices close to a known (calibrated) sensor and would need to run long enough to experience a range of environmental conditions (especially humidity).
Others have run this kind of study so we can lean on their conclusions but wouldn’t it be better to run our own? The difficulty is we only have one calibrated device and that is Freetown Way (Hull). I wonder if we could get permission to co-locate some devices there?
Please voice your thoughts.
