description: This thesis is dedicated to the research of the influence of the number of measurement sensors and the number of sensor measurements on the accuracy of the result. A device for determining the magnetic field based on MEMSmagnetometer readings has been developed. The concept and principle of operation of MEMS magnetometer, as well as the history of creation and development of MEMS sensors and their application in modern circuitry are considered A block diagram of the device containing 40 magnetic field sensors, a microcontroller and two stabilizers is designed; its main blocks and interfaces are described. The software of the device for working with the sensor LSM303DLH was developed. A schematic diagram of the device has been developed, which implements parallel connection of 40 lsm303dlh sensors to the stm32f205ret6 microcontroller. The device is powered through a USB port, and the power circuit contains the lm1117mpx-3.3/NOPB and LM1117MPX-1.8/NOPB stabilizers. The device's printed circuit Board was traced, according to GOST. The printed circuit Board was installed. The device software for working with the lsm303dlh sensor has been developed. Experimentally confirmed the operation of the device in the study of changes in the magnetic field strength by sensors at a distance from the conductor through which the current flows.
