Current measurement in power electronic systems is a necessary part of the measurement process. There are different ways for current measurement like using current transformers or using the Rogowski coils which are not precise enough in many applications and not suitable for use in power electronic measurement systems. For that reason, the Hall effect-based sensor can be used as a very precise alternative with minimum external components. Presented in this paper is utilizing the Hall effect current sensor ACS712 for current measurement with a microcontroller system. The measurement with the Hall effect sensor is described with an appropriate comparison of the measurement values on a microcontroller system and multimeter and high precision power analyzer Chauvin Arnoux 8335.
