Medium-Large Seed Types Planter Sensor

Hy Rate Population Sensor


The Hy Rate™ 3 LED Population Sensor is the sensor of choice for large seed types and seeding rates of 1 to 135 seeds per second with up to 98% accuracy depending upon the application of the sensor. Examples of these include: corn, soybeans, sunflowers, sorghum, sugar beets, and edible beans. Using optical technology, the seed sensors work under the principal of photo detection. Light emitting diodes (LEDs) create a thin field of light across the interior of the seed tube. A photo detector on the opposite side of the tube continuously monitors the intensity of the light. Any seed that disrupts the sensing zone’s light source is detected by the photo detector cell and the corresponding seed pulse is communicated to the monitor.
