<p>The door handle has a measuring electrode (4) and a reference electrode (5) to detect the presence of the user. The handle has conductors (7) positioned at least part facing one of the electrodes to create a capacitive coupling. The size and shape of the conductors is chosen so that the conductors and the electrodes form by electromagnetic coupling a zone (9) detecting the presence of the user.</p> |
