Abstract
Seed sensors that surround the conventional mounting location on existing seed tubes. The seed sensors sense seeds using electromagnetic fields, including RF and microwave fields. In one embodiment, a first seed sensor has a coaxial Fabry-Perot resonant cavity which is formed between two coaxial portions of a conduit that surround the seed tube. Another seed sensor uses a capacitive design. In one embodiment, the driving signals are applied 180 degrees out of phase. The detected phase shift between the reference and reflected signals provides reliable seed counting. Electronics extract the signal from the sensing field.
