Abstract
An electronic control device for the contactless control of a unit, e.g., a plumbing unit, especially a urinal, with at least one transmitter for sending directed light signals, and with a receiving device. The receiving device receives signals reflected from a scanned object and sends them to a circuit acting on the unit. The transmitter and the receiving device form an optical triangulation arrangement, wherein reflections are received from the background and from a predetermined detection zone to mask the said background.
