Title: SENSOR ASSEMBLY FOR DETECTING THE MOVEMENT AND/OR THE PRESENCE OF A PERSON
Abstract:
The invention relates to a sensor assembly for detecting the movement and/or the presence of a person, having a housing (1) with an opening (2) for electromagnetic radiation of a first type and electromagnetic radiation of a second type, a sensor (3) which is arranged in the housing (1) for detecting the electromagnetic radiation of the first type, and a shading element (5) which is arranged on the housing (1) so as to partly shade the opening (2). The shading element (5) has a degree of transmission which is less than 30% for the electromagnetic radiation of the first type, and a transmission and/or receiving element (6) is provided which is arranged in the housing (1) for transmitting and/or receiving the electromagnetic radiation of the second type, wherein the shading element (5) has a degree of transmission which is greater than 60% for the electromagnetic radiation of the second type.
