Abstract
A device for controlling a driven movement element with an electronic unit is proposed, which comprises a transmitter for electromagnetic radiation, for example, light, in particular infrared light, and a receiver for electromagnetic radiation emitted by a transmitter for the detection of objects on a propagation path between transmitter and receiver. According to the invention, the electronic unit is designed to detect a temporal change in at least one feature derived from the received electromagnetic radiation and, upon a detection of a change in the at least one feature that is comparatively slow over time, to output a signal that is associated with a detection of smoke.
