The present invention relates to a device for measuring the capacitance between two electrodes (4,5), for measuring the capacitance between two electrodes (4,5), 2 a downstream of the measurement circuit of the electrodes (4, 5) (6), downstream of the communication unit of the measurement circuit (6) (7), is connected to the communication unit (7), at least one turn and coil-like structure a first antenna (8), whereby the communication unit (7), a first antenna which is a reading received, to transmit to an external data communication unit (40) (8) It relates to a device equipped with. According to the present invention, apparatus of the present invention is connected to a measuring circuit (6), a second antenna having at least one turn and coil-like structure (9), whereby the second antenna (9 If) is excited by the alternating electromagnetic field, the so AC current is applied electrodes (4,5), connection portions of the second antenna (9) is directly or indirectly connected to the electrodes (4, 5) has a to have a second antenna (9). According to the present invention, the measurement circuit (6) is configured to an alternating current flowing through the AC voltage or the electrode according to the electrode (4,5) (4,5) directly or indirectly measured, the measurement the output of the circuit is adapted to be fed directly or indirectly to the communication unit (7).
