ABSTRACT:
An apparatus for controlling and sensing a closure member (20) movable between an open position and a closed position, more particularly an electrically powered window pane (20) of a motor vehicle (10) is provided with a sensor. The sensor comprises a sensor electrode (40) generating an electric field (F) in an opening range of the closure member (20) and a controller (22) connected to the sensor which senses any change in capacitance of the sensor electrode (40) in providing a control signal. For detecting a film of moisture (23) formed by condensation on the closing member (20) by simple and relatively low-cost means, the controller (22) detects a change in capacitance of the sensor electrode (40) caused by the presence of a film of moisture (23) on the closure member (20).
