Current Measurement Device Design Based on MSP430 Single-Chip Microcontroller

摘要

To measure high-current, contacting with the wire directly is a certain danger. This article describes a pincer current transformer what the principle of electromagnetic induction be used in, using non-contact of the current measurement methods. In addition, the current strength meter site may not be the city's conditions. In this paper, CPU used in this design of instruments is made by the U.S. company Texas Instruments, msp430f437, which is An ultra-low power microcontroller and Particularly suitable for battery-powered or hand-held device.
