A current transformer is a type of instrumental transformer specially designed to transform alternating current in its secondary winding, and the amount of current produced is directly proportional to ...

The Sonoff doesn’t use the ESP’s ADC pins, so he’s broken one of them out on a lead to a current transformer which ... incorporating an ESP port of an Arduino current sensing library.

As a result, ECT has been considered as the appropriate substitute of the traditional electromagnetic current transformer. But the ECT is new equipment in power system, so the interfacing technology ...

with the goal of interfacing with an Arduino-based user-friendly microcontroller. We found that a galvanostatic electrochemical method yields the highest peak current of 10 mA, promising a highly ...
