I need to get several current sensors to take measurements in my system at relatively high current levels. I found two sensor packages available that have similar specs:
ACS711EX for +/- 31 A for $3.95 https://www.pololu.com/product/2453
ACS714 for +/- 30 A for $8.95 https://www.pololu.com/product/1187
I read through both descriptions and the differences seem minor, and the cheaper one actually has a extra feature of a fault output. I’m trying to understand what the rationale for choosing one versus the other is, and what the extra benefits are of going with the more expensive option.
