The circuits here are just a few examples of how the Hall effect sensor can expand the scope of your experimentation. Research is constantly improving Hall effect sensors and the future looks amazing.

The linear current sensor consists of a precise, low-temperature drift linear Hall IC with temperature compensation circuit and a current path with 98mΩ typical internal conductor resistance.

Melexis has squeezed a magnetic circuit inside an SMD package to get a end-sensitive Hall effect latch for slim-line motor applications. “We’ve responded to the automotive industry’s demand for more ...

But, Hall-effect current sensors have traditionally exhibited significant drift over temperature and lifetime.
