Cautions about using the Sensors
[Handling the temperature-humidity sensor]
- The service life of humidity sensors can vary greatly depending on
operating environment.Periodic calibration may be required.
During use the temperature-humidity sensor will accumulate impurities (dirt)
on the surface of 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°C 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.
Wetness Detection Sticker

-Wetness Detection Sticker
Informs you that the sensor has been wet.
Normal
Abnormal
Under normal conditions, black
dots will appear on a white
Under abnormal conditions, it will
turn to red.
-Temperature Detection Sticker
Informs you that the sensor measured a temperature measurement over 60°C.
