Modified optical sensor based seed counter for seed drill

Author(s): Venkata Reddy HK, Vinod Kumar S and Anand BA
Abstract: Seed drill is an improvised agricultural implement which is used for sowing seeds into the soil at required depth and distance. Now a day’s seed drills become more common for sowing. The calibration of seeds and seed rate determination is very tedious and time consuming in agricultural practices both for small and large farmers. To overcome this tedious work, seed counters are designed and developed to do count seed and calibrates in easy and accurate way. This research involves design and development of digital seed counter to provide accurate seed counting procedure at affordable cost and efficiency. The complete process is controlled using a micro controller and it performs all the operations in a sequence. This seed counter, eliminates operator error and reduces operator fatigue. Light reflecting optoelectronic field counter capable of detecting and counting free falling object with equivalent length/diameter >than or = 0.5 mm in seed delivering tube was developed and tested to evaluate seeding rate. The performance of the device is not affected by the shape and color of the counted objects. An electronic device for counting seeds in the size range from flax to groundnut has been developed. The accuracy of counting is very high, for the tested results. The speed of counting varies from 200 to 300 seeds per minute. In this electrical sensor seed counters can use in laboratories, to count seeds per corn, ear heads etc. The overall accuracy of the seed counters is 99.85% at travel speed of 2.5 Km/h.
