Appendix A: UWBT-RH Sensor Information
A.1 Accuracy
Figure A-1. RH Accuracy Chart
Figure A-2. Temperature Accuracy Chart
Accuracies are tested at Manufacturer’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.
A.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 H.4
“Reconditioning Procedure” to accelerate eliminating the offset. Prolonged
exposure to extreme conditions may accelerate aging.

A.3 Storage Conditions and Handling Instructions
It is of great importance to understand that a humidity sensor is not a normal
electronic component and needs to be handled with care.
Chemical vapors at high concentration in combination with long exposure times
may offset the sensor reading. For these reasons it is recommended to store
the sensors in original packaging including the sealed ESD bag at following
conditions: Temperature shall be in the range of 10°C – 50°C (0 – 80°C for limited
time) and humidity at 20 – 60%RH (sensors that are not stored in ESD bags). For
