    Hi,

    I've come accross this component:
    http://www.nuhorizons.com/products/NewProducts/Nexus/Allegro/index.html

    Which says that it uses a hall effect sensor to measure the current.

    In theory, if I were to tape a hall effect sensor to the wire, would it work
    just as well? Obviously it would take a bit of calibration, but would that
    be the only difference?

    Cheers,

    Michael
     
  2. Hall effect devices can be used to measure Lorentz force. That's how a
    clamp on ammeter works. You'd actually be measuring the voltage produce
    by the Hall effect sensor which increases with current increase.
