<p>A device (1, 100) for sensing the presence of an object in a storage compartment (40), particularly a minibar, is disclosed. 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 said electrodes (5, 6). The device (1, 100) further includes electronic processing means interacting 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.</p> |
