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 RHT03's sensitive-elements and debase RHT03's sensitivity.

(3) Disposal when (1) & (2) happens

Step one: Keep the RHT03 sensor at condition of Temperature 50~60Celsius, humidity <10%RH for 2 hours;

Step two: After step one, keep the RHT03 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.

RHT03 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 RHT03'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 RHT03 may

cause personal injury.
