Does the moisture/humidity sensor need calibration prior to installation, or at any point during its service life?

The moisture sensor is tested for functionality in Germany and does not require further calibration. The measurement values are referenced in the software. There are scientific and practical approaches here: Scientifically, the sensor is referenced in the software to the surrounding material in which it is installed, and the software is adjusted accordingly for the most accurate moisture measurement. However, in practice, it is crucial for the moisture sensor’s purposes to detect trends and observe drying or moisture increases. Therefore, the development of moisture trends is more important than knowing whether there is 1.925% or 2.0123% moisture in the structure. Hence, there is the option to adjust the software to the surrounding material, but the trends and early indication of abnormalities are crucial.
