how do u get a mainspower plug through that tiny hole?
that sparkfun sensor can b integrated easier, i guess...
one just snaps it on the mains power line...
possibly u just measure the reactive power?
i have no idea how that sensor works, when there r 2 wires with the same current (just the direction is the oposite)...
i think u should wait for the high voltage experts... they should b here within a day...
I have a cable with a plug i can easily remove. I don't need the plug to go through the hole. I only attach it after the cable passing the hole.
I think the basis of work are the same, but i have this one and it was rather expensive. I want to see if i understand it...
I'm not measuring power. I'm just looking for the current. Only one of the cable go in the hole, otherwise the sensor would give zero Volts at the output.
