Abstract

A capacitor electrode (21,23) is arranged in a passenger waiting area (11) outside the lift cabin. An evaluation and control circuit (25) produces a lift control signal for controlling the travel of the lift cabin based on the detected capacitance of the capacitor electrode. The electrode is a floor electrode or wall electrode. An independent claim is included for a further sensor.
