Characteristics
The average increase of capacitance over the
working range is 140 pF for the HC1000 and
56 pF for the HC101. For the range of 0–98
%RH, linear approximation is possible, errors
will be lower than ± 1.5 %RH.
The sensor characteristic is described by the
following linear formula:
C(RH) = C76 * [1 + HK * (RH – 76)]
with HK = 2800 ± 120 ppm / %RH

relative humidity [%RH]
For high accuracy requirements, the sensitivity is described by the following polynom:
C(RH) = C76 * [1 + HK * (RH – 76)+K(RH)]
where:
K(RH) = A1*RH+A2*RH1.5+A3*RH2 +A4*RH2.5
A1=2.1159E-3
A2=-7.6305E-4
A3=8.9470E-5
A4=-3.4130E-6
