The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure ...

ACS37030 and ACS37032 employ dual signal paths, with one capturing low-frequency and dc current using Hall-effect elements, and the other using an inductive coil to capture high-frequency data. The ...
