| Abstract: | A high accuracy intelligent magnetic field measurement instrument with communication interface controlled by microprocessor was designed in this paper. The magnetic field induced signal was derived by two coupled integrated hall sensor and the analog signal was converted to digital signal through a voltage to frequency converter. The instrument was calibrated and the experimental data indicated its measurement accuracy is 0.1 mT. This instrument can not only measure the magnetic fields precisely, but also achieve networked remote supervisor to electromagnetic radiation of wireless communication base stations. |
