Abstract
An optical seed flow monitoring system for monitoring seed flow through the primary and secondary seed tubes in an air seeding system. The primary seed tubes include a primary seed sensor having a plurality of emitter lens bodies and receiver lens bodies. Optical fibers connect the emitter lens body to an optical beam generating device and the receiver lens body to an optical beam detecting device both positioned remotely from the seed tubes. Alternately, one or more of the secondary seed tubes can include a secondary seed sensor having an emitter lens body and a receiver lens body.
