Abstract

The invention relates to a device for detecting (CAPT) the presence of an object, that comprises at least one detection member (EA, EB) to which is associated a physical value that varies based on the environment in which said detection member (EA, EB) is located. The invention is characterised in that the physical value provides a variable reference level corresponding to the absence of an object and in that it further comprises a saving device (LOG IC) for saving, upon the emission of a low-frequency signal, a value of the reference level measured before the emission of said low-frequency signal.
