Design and Implementation of a Close-Loop Hall Effect Sensor for the Measurement of Instantaneous Current and Voltage

The growth of every economy relies heavily on the availability and proper management of electrical energy in industrial and domestic applications. This growth necessitated the need for efficient and accurate measurement of electrical energy. In this paper, the principle of Hall Effect was deployed in the design and implementation of a low-cost close loop Hall Effect sensor for measuring instantaneous current. The output of the measurement is visualized through an LCD and can be interfaced to a PC for real-time graphing. The calibration result showed that the developed system has a relative error of 5.30% and can measure up to ±127.39 Ampere
