Abstract: A capacitive detection device includes a set of several detection electrodes for each carrying out capacitive detection at a detection location. Each detection electrode is formed by at least a first measurement electrode and a second measurement electrode. The device also includes first detection electronics forming, with the first measurement electrodes, a first measurement channel, independent from a second measurement channel formed by second detection electronics with the second measurement electrodes.
Therefore, for each detection location, the detection device carries out at least two redundant and independent detection operations.
