hello,

is it for DC or AC current ?

for DC current, you better have to use Hall effect sensor
a built-in device as LEM Sensor
or build yourself one ..as an exemple on my web page : **broken link removed**

I want to measure Mains AC Current. But Using a current transformer and scaling down and converting to DC.
