Research and development of monitoring software to measure and save data of the Earth’s magnetic field for NICA-MPD-PLATFORM. Due to the presence of unwanted background magnetic fields or uniform magnets with defects in their magnetic field, that could affect measurements, it was necessary to create magnetic field monitoring system. For that purpose a system was created with use of magnetometer MAG3110 and NI myRIO. The software to collect and record magnetic field in three axes with the option of changing the frequency and number of measurements was created. The final program can also calibrate raw data.
