| Abstract | ||||
| New light reflecting optoelectronic fields counter capable of detecting and counting free falling object with equivalent length/diameter ≥0.5mm in seeder delivering tube was developed and tested to evaluate seeding rate. The performance of the device is not affected by the shape, and color of the counted objects. Accuracy is dependent on seeding rate, and falling seeds overlapping. The device can count falling seeds with 0.11 sec apart accurately, or seeding at speed ≤ 6km/h within 5cm diameter of seeds delivering tube. | ||||
