The Application of Optoelectronic Elements to Control the Sowing Process

Abstract

The article is an overview of scientific and patent literature as well as solutions available on the world market of electronic equipment for seed drills. Recently Dickey-John and Väderstad, which offers the SeedEye system, have been leading companies in this branch. Photoelectric sensors, which do not interfere with the seed flow, are often used to count seeds and control the correctness of sowing. The article describes and presents the results of simulation and laboratory tests of two original innovative concepts of a photoelectric sensor: 1 – with an infrared diode and a centrifugal seed stream concentrator, 2 - laser multi-reflection sensor
