Due to a constant overtemperature of the humidity sensor, its dewing is significantly impeded or prevented within the system limits.
A faster reaction speed to humidity fluctuations is achieved, even in the range above
in the range above 95 % RH. The sensor (combined humidity and
temperature measuring element) is heated approx. 3 K above the ambient temperature.
From the measured relative humidity at overtemperature,
the chip temperature
of the sensor and the ambient temperature (via a second, separate
temperature measuring element)
the actual relative humidity is determined.
