Abstract (en)
[origin: WO9946743A1] The invention concerns an electronic sensor in particular for detecting theft or loss of objects comprising a central electronic unit (1) exchanging coded data by radio frequency with at least a transponder (11), associated with an object to be monitored to verify its presence in a located volume (12) and emitting an alarm (13) when said transponder (11) is no longer present in the monitored volume (12). The invention is characterised in that said transponder (11) is automatically set in stand-by mode outside the transponder active phases (11) and the central unit (1) selectively corresponds with said transponder.
