8.5 Temperature/Humidity Sensors Specifications
88
Lifespan of the temperature/humidity sensor
The time to replace the temperature/humidity sensor is approximately one year.
In order to maintain measurements within the accuracy specifications, it is recommended to
replace the temperature/humidity sensor with a new one after using it for one year.
Immediately after starting to use the temperature/humidity sensor, impurities will attach to
its surface and it will start to deteriorate.
It can be used again by drying it even after condensation and water droplets have attached
to the surface, but as dust and dirt are attached to the surface together with the water,
impurities will remain even after the water has evaporated, accelerating the deterioration of
the sensor. In particular, the sensor may experience deterioration of its features or damage
within a year when used in a smoky or dusty environment, an atmosphere with chemical
solvents or corrosive gases, or an environment of high temperature/humidity (above 50 C,
60% RH).
