We are working on a project. Our goal is to measure the DC current of a cable ranging to 1A-50A. However the hall meter doesn't seem to react at all when putting a cable with 2A close to it. We get a voltage difference with a strong Magnet.
How do we go on from here? How do we amplify the signal enough for us to notice it? Do we need an instrumental amplifier?
We are using Arduino UNO.
