Hi, I'm interested in having my raspberry pi know if my 120v sump pump is operating. The pump draws 4A when operating. Could I detect the current with a hall effect sensor? (it's a A1120LUA-T) I'm thinking of opening up a power strip and placing a hall effect sensor in there. I'm guessing the magnetic field would not be strong enough to detect simply by placing the sensor on the wire. I have an inductor core I removed from a desktop PC, could I use that to enhance the magnetic field?
If this won't work, I'm thinking of building a current transformer using this inductor core. Or maybe buy one like this?

Or this would probably be easier to use, since it has a lot more on board circuitry. Although I don't quite understand how to use it, I don't understand the 3A/15v figure they are talking about.

I would like something small that fits inside a power strip.
Thanks.
