I took that from Sensirion web site.Pretty cool that it has an SHT30. (...)
FineOffset installs SHT30 but in Ambient WS2902 there is another sensor from the bottom shelf.
If it was SHT30 then the accuracy should be:
temperature: +/- 0.2° C
(RH) humidity : +/- 3%
and
in the Ambient WS2902 manual - page 48 - there is a record:
temperature: +/- 2° C
(RH) humidity : +/- 5%.
Ask Ed to explain it
The specs can be interpreted in different ways as CW2274 mentioned.
The Davis stations use the analog version of the 31.
No sir, it's digital, just a different protocol than the 35. That's why us mere mortals can't adapt it.
