Cautions about using the Sensors
When using the Temperature/Humidity Sensor HHA-3151, please
take note of the following:
The sensor can measure temperature within the range of -30 to
80°C and humidity within the range of 0 to 99%RH. Only use
the sensor within these measurable ranges.
If extremely severe temperature changes occur, the humidity
measurements may appear abnormal. Once the sensor's
temperature becomes stable, the measurements will return to
normal.
During use, the surface of the temperature/humidity sensor will
accumulate impurities (dirt) causing a decrease in the sensor's
accuracy and sensitivity. If the sensor is being used in a bad
environment (smoky or dusty places) it may be necessary to
change the sensor sooner.
This temperature/humidity sensor is not waterproof. If the
sensor gets wet, immediately remove the sensor from the Unit
and wipe it with a clean cloth as soon as possible. Then allow
the sensor to dry in normal room temperature before using it
again.
Do not expose the temperature/humidity sensor to a strong
impact. This may effect measurements or cause damage,
including malfunction.
When the sensor is not to be used for a long period of time,
please store it at normal temperature and humidity.
