[ Handling the temperature/humidity sensor]
- The temperature/humidity sensor should be changed after a period of about
one year. After removing the sensor from its package, please change the
temperature/humidity sensor after one year’s usage.
During use, the temperature/humidity sensor will accumulate impurities
(
dirt) on the surface of the sensor causing the sensor's accuracy and
sensitivity to decrease. If the sensor is being used in a bad environment
(
smoky or dusty places) it may be necessary to change the sensor sooner.
- When the temperature/humidity sensor is not being used, please place it in
the attached vinyl bag with the drying agent included and store it in a cool
dark place with a temperature of between 5 to 25℃ and a humidity of below
30％ RH.
- Attached to the temperature/humidity sensor are two stickers: a wetness
detection sticker and a temperature detection sticker. If either of the sticker
shows abnormality, you should change the old sensor with a new one
immediately.
