The humidity sensor SHS-A4 is a resistive dew formation sensor with miniaturized dimensions for detecting the onset of condensation. The exponentially rising resistive characteristics in the upper humidity region facilitates simple signal processing and a stable switching behavior on dew formation threshold.
The humidity sensor SHS-A5 is a combined sensor for detecting the onset of condensation with additional interdigital structure (conductance sensor) for detection of liquid water or condensation.
