Handling the temperature
/
humidity sensor
】
●
The temperature
/
humidity sensor should probably 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 stickers
shows abnormality, you should change the old sensor to a new one
immediately.
