Capacitive Relative Humidity Sensor
The operating principle of capacitive relative humidity sensors
are based on the hygroscopic properties of their polymer,
which is used like a dielectric in a capacitor. The polymer
gets in equilibrium with its humid environment quickly, and
reversibly, and changes its capacity value depending on the
humidity level.
