Characteristics
The average increase of capacitance over the
working range is 55pF. For the range of
0–98% RH linear approximation is possible, errors
will be lower than < ± 2% RH.
The sensor characteristic is determined by the
following linear formula:
C(RH) = C₀ * [1+HC₀ * RH]
with HC₀ = 3420 ± 250 ppm /% RH
relative humidity [% RH]
For high accuracy requirements, the sensitivity is determined by the following polynomial:
C(RH) = C₀ * [1 + HC₀ * RH + K(RH)]
whereby:
K(RH) = A₁*RH+A₂*RH^1.5+A₃*RH²+A₄*RH^2.5
A₁ = 2.6657E^-3
A₂ = -9.6134E^-4
A₃ = 1.1272E^-4
A₄ = -4.3E^-6
