Beware of the output voltage: as I received the sensor, it was outputting 110mV/A, which is around 13.2V at 120A. I reduced the output resistance (see data sheet INA139) from 100k stock to 10k. that gives me around 1.1V for 100A, which is what I needed for the arduino internal reference voltage (1.1V). If you want to use it with BF, consider 33k, or even 27k if you want to use the full 120A scale.

  • mux001 Because a voltage divider on the output is too mainstream :D
