10 dBm

The default 20 dBm must be changed to 10 dBm to comply with power level
regulations. The 0.5 dBm variation depends on the internal DC power used
(3V, 3.3V, 3.7V max) of the different models.

Temperature Accuracy Chart

Accuracies are tested at Manufacture’s Outgoing Quality Control at 25°C (77°F) and 3.3V.
Values exclude hysteresis and non-linearity, and is only applicable to noncondensing
environments.
I.2 Operating Conditions
Sensor works stable within
recommended normal range – see
Figure. Long term exposures to
conditions outside normal range,
especially at humidity >80%RH, may
temporarily offset the RH signal (+3
%RH after 60h). After return to normal
range it will slowly return towards
calibration state by itself. See
Section I.4 “Reconditioning
Procedure” to accelerate eliminating
the offset. Prolonged exposure to
extreme conditions may accelerate
ageing.
