Hello

I should measure battery charging and discharging current, battery is big (forklift, 48V 400 Ah), so charging current can be 50...100 A

disharging can be ~200 A. I have seen some sensor which can measure current from outside of cable (without shunt resistor) but

can't remember type of sensor.

Sensor should be suitable for fixed installation, bolted (or glued) to battery.

Allegro Micro (mentioned by valusoft) do a number of sensors targetted at "automotive" applications - that would be the kind of place to start...

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
