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.
