A motion sensor device for detecting a detection object in a detection region, with
detector means (12) which are arranged in a sensor housing (10) and designed for detecting motions of the detection object, as well as for generating an electronic distance
signal (a) and angle
signal (phi) corresponding to the detection object, wherein the distance
signal (a) corresponds to an instantaneous distance of the detection object from the sensor housing (13) and the angle signal corresponds to an instantaneous
position angle (phi) of the detection object in the form of an
azimuth angle in a plane of motion of the detection object extending parallel to the ground surface in the installed state of the motion sensor device on a wall and
signal processing and control means (14) connected downstream of the
detector means are designed for activating a device (11) to be connected downstream of the motion sensor device in dependence on the distance signal and the angle signal, and wherein the
signal processing and control means
feature detection region determining means (16) with an interface unit (18; 20), which can be adjusted, configured and / or actuated by a user and serves for at least sectionally adjusting and / or defining a boundary of the detection region in the plane of motion, wherein the
signal processing and control means feature comparing means (22), which are designed for comparing a distance signal and angle signal generated for a detection object by the
detector means with data on a predefined or adjusted boundary of the detection region that can be variably defined and / or adjusted relative to the sensor housing frontally (32) and laterally (30, 34) in the plane of motion, wherein display and / or
visualization means (26) are assigned to the interface unit (18) in order to optically display and / or output the boundary.
