PCT No. PCT/FR96/01612 Sec. 371 Date Apr. 10, 1998 Sec. 102(e) Date Apr. 10, 1998 PCT Filed Oct. 16, 1998 PCT Pub. No. WO97/14335 PCT Pub. Date Apr. 24, 1997A device (1, 100) for sensing the presence of an object in a storage compartment (40), particularly a minibar. The device (1, 100) includes a set of capacitive sensing modules (3) each comprising two electrodes (5, 6) adjacent to a holder for an object (46), and an oscillating circuit including the capacitance between the electrodes (5, 6). The device (1, 100) further includes electronic processing which interacts with each capacitive sensing module in order to output sensing signals indicating the presence or absence of objects on each holder, and to provide a capacitive signature of the objects. The device is useful in storage equipment, particularly in hotels.
