Current measurement is presently possible through a number of different techniques, including resistive sensing, current transformers, and magnetoresistive sensing. The measurement of current using Hall-effect sensors is possible but not with high precision over a large temperature range. Through laboratory experimentation and research, this project details the characterization of a Hall-effect sensor and provides current measurement results over a range of -6A to 6A that are accurate within 1% over a temperature range of -25C to +85C.
