  • Good hall-effect sensor

    posted by kirovclass on 02:30:01 G12T 04/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Tiny board, a good choice if somebody is looking for a cheap hall-effect sensor to monitor currents.

    Cons: The clearance between PCB traces in the input section is quite small (under 1mm), so I would not dare to use it as it is at mains voltage (or even above ~50V). Safety first!

    Other: The ACS712 is a very good chip for doing current sensing, and this simple board allows it to use it a very simple way.
