stamp friendly current sensor

icepuck

Does anyone know of a current sensor module that could be use with a bs2 or bs2px?
Something in the 0-50amp dc range would work. Google seems to be lazy tonight or I'm not using the right words.

AC or DC?

A 0.01 ohm shunt would produce 0.5V at 50A

Dc-up to 12-24volts.

kwinn

A shunt resistor and op amp or comparator for feedback or on/off control.
A shunt resistor and an adc/dvm chip if you need continuously display or digital measurement.
A shunt resistor and meter or hall effect clamp if just taking occasional measurements.
