Using a sense resistor is only the first step in the current-sensing decision. The other part is topology: whether to use ...

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 ... ESP port of an Arduino current sensing library. To round off the ...

In the video after the break, [Xavier] goes over the theory of how it all works, but the short version is that you just need to use a Current Transformer (CT) sensor. These little devices clamp ...

While the excitement around EVs hitting a projected 157 million by 2030 is palpable, a less visible but equally ...
