Not sure if this is the right place for this, but here goes: I wish to be able to reasonably accurately measure large DC current (maybe 80 amps tops) relatively continuously on my arduino. I am considering this linear Hall-effect sensor.
My concern is that those leads from the terminals to the actual sensor chip, and even the lead-blocks themselves look mighty small for 80 amps, much less the 150 amps it is rated for. To safely carry 80 amps, I’d plan to use 4 Ga. copper wire. What am I missing here? I have no doubt it would handle 150 amps for a few seconds, but would it handle 60 - 80 amps for several hours without frying? Is there a better way, perhaps? Using a separate shunt seems more logical, but it looks like a PITA to set it up properly. I was hoping for more of a turn-key solution…
Any thoughts or advice appreciated! Thanks in advance.
