Abstract: A housing arrangement for a radar sensor includes at least one tubular body and a shielding device for radar beams. The at least one tubular body has a distal end which has a lens mounted therein, and a side wall. The shielding device is arranged on the side wall on an outer side of the at least one tubular body. The at least one tubular body is made of a dielectric plastic. The shielding device is made of a metal.

Abstract: A sensor device for determining a position of seeds while sowing. The sensor device includes a radiation assembly which generates an illumination radiation oriented towards a target area, and a detection assembly. The radiation assembly includes a radiation source which provides an emission spectrum of the illumination radiation covering a spectral range. The detection assembly includes a radiation detector which detects an incident radiation, and a filter member with an attenuation band and a pass band. The radiation detector includes a field of view. The pass band has an attenuation which is less than an attenuation of the attenuation band in a wavelength range where the wavelengths are longer than those of the attenuation band. The target area and the field of view intersect. The radiation source and the radiation detector form a triangulation arrangement so that a distance from the target area to the detection assembly can be determined.
