Abstract
A low-cost teslameter based on a Hall effect sensor MLX90242 is proposed in
this paper. The proposed teslameter is built around a PIC18F4550
microcontroller and it can measure magnetic flux density in the range
between -55 mT and 55 mT. Temperature stability of measurements originates
from the MLX90242 sensor itself. In order for the proposed transducer to be
accurate, it has undergone a calibration procedure using a highly accurate
teslameter employed as reference instruments and high-quality variable-field
electromagnet. The proposed teslameter can store measurements on a PC via
built-in USB communication.
