Abstract
The device has an optical scanning head (3) with a radiation source (17), as well as with a sensor (21). The scanning head (3) transmits a signal toward a background (9, 14), e.g., a washbasin, and receives signals diffusely reflected from that background. The signals (11) received are sent to an electronic control unit (22) for controlling, e.g., a valve (3). The device is arranged, e.g., in the water outlet (2) of a washstand appliance.
