Currently, the testing procedure for 3D Hall sensors at the MUSIC lab is time-consuming, labour intensive, and is susceptible to systematic errors. There is a need for an automated, accurate, and repeatable test setup for 3D magnetic sensor characterisation. That is why the objective of this thesis is to develop a control interface that allows users to define arbitrary magnetic field vectors and perform 3D magnetic field sweeps on a Hall sensor placed in a 3D Helmholtz coil. The development was performed in three stages: calibration of a 3D Helmholtz coil, development of a 3D magnetic field sweeping script, and validation of the system by benchmarking measurements from two commercially available 3D Hall sensors against known magnetic fields. The 3D Helmholtz coil was successfully calibrated, finding that the generated magnetic field strength of 2.87mT corresponds to the maximum relative uncertainty of 2%. A LabVIEW script was developed, enabling users to generate 3D static magnetic field vectors and 3D magnetic field sweeps with definable orientation, resolution and strength. Lastly, the system was validated using two commercial Hall sensors, confirming its stability and accuracy for testing other Hall sensors. This system can be used for repeatable magnetic sensor evaluation in research, with a versatility that can benefit various sensor configurations.
