Abstract. Most of the row-crop seeders with electric drive in the Russian Federation are produced abroad. This year, most foreign companies have limited their service in our country. The research was carried out with the aim of developing a software and hardware complex for a control and monitoring system for sowing of row seeders with electric drives. The work was carried out on the sowing section TS-M-4150. General control over the system was carried out using the Arduino UNO control board. Determination of the duration of the flight of seeds through the seeding sensor was carried out on soybean, corn, lupine, sugar beet. The developed algorithm of the program for accounting for skips, twins and crushed seeds was based on the analysis of the time of flight of seeds and the time interval between the flights of seeds through the sensor. Improving the seeding control system by supplementing it with an algorithm for comparing the period of flight of seeds through the sensitive element of the capacitive sensor made it possible to increase the accuracy of determining the coefficient of uneven seeding by 3%. When the seeder moved at a speed of 7 km/h and the sowing disc turns 60 rpm, the time spent by sugar beet seeds in the sensitive zone of the seeding sensors should be from 6 to 10 ms, and the time interval between the passage of adjacent seeds should be from 41 to 90 ms. The developed algorithms for controlling the rotation speed of the sowing disc depending on the speed of the sowing unit and automatically adjusting the position of the double remover will improve productivity, the quality of the sowing unit and reduce the labour intensity of work.
