A scheme of the measuring complex has been developed, in the conditions of operation of a laboratory vibrating screen with a vibroactive sowing surface developed by the department of MAMV UDUNT. The oscillation frequency of the screen elements is 25 Hz (1470 rpm) and the maximum amplitude is 4-5 mm). A comparative analysis of sensors-accelerometers and microcontrollers has been carried out. The proposed measuring setup uses the connection of 2 MPU 6050 or ADXL345 sensors to the Arduino Nano microcontroller. The measurement limit of these sensors lies within ± 16g, which corresponds to the operating parameters of the vibrating screen. Sampling frequency 1000 Hz. Sensors are connected to the microcontroller via the I2C interface. The frequency of data recording to the computer is in the range of 250-500 Hz. The necessary software has been developed.
