摘要：
1. A seed sensor for detecting the passage of a seed through a tube, comprising means for emitting radiation through the tube in two orthogonal directions； means for uniformly distributing radiation from said means for emitting radiation； means for detecting radiation transmitted through said tube in two orthogonal directions in such a way that the passing seed interrupts the radiation incident on the radiation detection means； means for determining the position of the seed in the sowing tube in two orthogonal directions. 2. The seed sensor according to claim 1, in which the means for detecting radiation includes two rows of radiation detecting elements located essentially perpendicular to each other, and the means for determining the position of the seed in the seed tube in two orthogonal directions includes limiting the radiation incident on each element detecting radiation by radiation traveling in one of two orthogonal directions. 3. The seed sensor assembly for determining the passage of the seed through the seed tube, while the seed tube has spaced front and rear walls and spaced side walls, this sensor assembly contains a radiation source on one side wall of the seed tube； a diffuser for evenly distributing radiation from said radiation source； a number of elements detecting radiation along the side wall opposite the radiation source, and passing from the front wall to the rear wall of the seed tube； means for arranging the radiation received by the detecting elements, so that each element receives1.
