The IR940 infrared seed rate sensor is an economical solution for counting seeds of row crop seeders. Measures the amount of seed and gives the operator confidence that the seed is being sown. Seed seeding control sensor IR940, universal, the maximum number of seeds counted is up to 400 seeds per second with an accuracy of up to 98%, depending on the application of the sensor. Examples: corn, soybeans, sunflowers, sorghum, sugar beets and edible beans... Using optical technology, seed sensors work on the principle of photodetection. Infrared light emitting diodes (LEDs) create a thin field of light throughout the inside of the seed tube. A photodetector on the opposite side of the tube continuously monitors the light intensity. Any seed that disturbs the light source is detected by the photodetector cell and the corresponding pulse is transmitted to the monitor. Comes with 3 infrared LEDs to ensure accurate seeding speed.
