Abstract
A humidity sensor which may be tested after installation including: a first electrode having a first surface material; a second electrode having a second surface material that is different from the first surface material such that an electrical voltage is generated when the first surface material and the second surface material come into contact with a humid medium; a voltage-increasing device; an energy storage device for storing the electrical energy provided by the two electrodes; and a transmitter unit for wirelessly transmitting information, wherein one of the electrodes is shaped as a coil which is electrically connected to a capacitor in order to form a resonant circuit so that, in a test state of the humidity sensor, the resonant circuit can be excited by an external high-frequency signal in order to generate the electrical supply energy for the control device in order to provide a test signal.
