8. Attentions of application:
(1) Operating and storage conditions
We don't recommend the applying RH-range beyond the range stated in this specification. The RHT02 sensor
can recover after working in abnormal operating condition to calibrated status, but will accelerate sensors' aging.
(2) Attentions to chemical materials
Vapor from chemical materials may interfere RHT02's sensitive-elements and debase RHT02's sensitivity.
(3) Disposal when (1) & (2) happens
Step one: Keep the RHT02 sensor at condition of Temperature 50~60Celsius, humidity <10%RH for 2 hours;
Step two: After step one, keep the RHT02 sensor at condition of Temperature 20~30Celsius, humidity
>70%RH for 5 hours.
(4) Attention to temperature's affection
Relative humidity strongly depend on temperature, that is why we use temperature compensation technology
to ensure accurate measurement of RH. But it's still be much better to keep the sensor at same temperature when
sensing.
RHT02 should be mounted at the place as far as possible from parts that may cause change to temperature.
(5) Attentions to light
Long time exposure to strong light and ultraviolet may debase RHT02's performance.
(6) Attentions to connection wires
The connection wires' quality will effect communication's quality and distance, high quality shielding-wire is
recommended.
(7) Other attentions
* Welding temperature should be bellow 260Celsius.
* Avoid using the sensor under dew condition.
* Don't use this product in safety or emergency stop devices or any other occasion that failure of RHT02 may
cause personal injury.
