Hi,
being a new "user" to the world of electronics, I can't get my head on prettty common things (or at least I think so)
How is one of this sensors "using one option" rather than another one? Does it change automatically?
Is there a different phisical product for each option? Or maybe it depends on the input voltage or something you need to change manually
(sorry for my bad english, I hope it's clear anyways)
