Since I own a scope, I kind of always wanted to measure mains current. Today I asked myself, If it would be possible to make a reasonably accurate current sensing extension cord with a BNC connector for my scope.
Now I just wanted to ask, If measuring current with a halleffect sensor has any flaws, or is as easy as it sounds like
I already created a list for the components I need:
One cheap extension cord (with phillip screws)
A halleffect sensor
A BNC connector
a powersupply for the sensor (probably some 12VDC LED power supply which I will hide inside the extension if possible)(and also a accurate voltage regulator)
I already have the coil, but I'm not quite sure if 15 turns of 1mm insolated copper wire around a 1cm (diameter) ferrite core will do it. It generates near to no heat at 5A continuously.
So, is this as easy as it sound or are there some flwas in my plans?
