HUMIDITY OPERATING CONDITIONS
 RH Operating Conditions

The humidity sensor may be used in a range of 0…100% RH but the recommended range is reduced at elevated temperatures. This is due to the fact that quite an aggressive environment is developed when you are measuring at high humidity and at the same time at a high temperature.
