Abstract (AI)
In this paper, a DC digital gaussmeter for measuring magnetic fields up to ±1000 G(±100 mT) is presented. It consists of two interchangeable transverse magnetic field probes based on Hall-effect sensor integrated circuits (ICs), a data acquisition module developed around a 8-bit PIC18F4550 microcontroller, a standard 2×16 character LCD display and a 5 V power supply module operating from 6 AA batteries. The instrument features USB connectivity and LabVIEW software for PC remote control. The gaussmeter is suitable for a full range of DC magnetic field measurements, and can be used for both research and teaching activities.
