That would appear identical to what he has, he would still need a magnet/transducer of some kind?As Mike indicated, building your own Hall effect current sensor would take a little bit of work. Why not consider this: https://www.sparkfun.com/products/8882?gclid=CImwlqyD68kCFUWVfgodF1wBBA
...the simple answer is yes you can. To get started read about the principles, there are loads of examples online:could i use this sensor oh49e to measure current ranging from 0-5 A to monitor it on lcd using microcontroller?
