Hall sensors versus shunts?
I was looking into a current sensing method for my universal PIC PWM controller.
I was wondering if I could use a Hall sensor.... Advantages of using the Hall sensor, is more output signal, and DC isolation.
A shunt method needs: 1 opamp, 1 shunt, some resistors, and perhaps capacitors. A PCB mount Hall sensor module only needs itself.
Found this on line: closed loop Hall sensor, about 8 Euro:

and this one, open loop, more drift, about 6 Euro 50:

Both would seem to fit nicely?
Has anybody here any experience with hall sensors, and what about drift and open - versus closed loop performance?
I may just order some to try it out.
