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.

基于霍尔效应传感器MLX90242的低成本teslameter

本文提出了一种基于霍尔效应传感器MLX90242的低成本teslameter。所提出的teslameter是围绕PIC18F4550微控制器构建的，它可以测量-55 mT和55 mT之间的磁通密度。测量的温度稳定性来自MLX90242传感器本身。为了使所提出的换能器准确，它已经经历了一个校准程序，使用高精度的teslameter作为参考仪器和高质量的变场电磁铁。所提出的teslameter可以通过内置USB通信将测量结果存储在PC上。
