摘要：
A seed sensor system determines the position of the seed relative to the seed tube as the seed passes the sensor. The position of the seed as well as the speed of the planter and the position of the seed tube above the planting furrow are used to calculate trajectory of the seed into the furrow from which the seed spacing is predicated. By sensing the seed in both X and Y directions in the seed tube, the sensor is better able to determine multiple seeds as well providing more precision to the seed population.
