so we have sensors. great.
but, what do they sense?
how?
most important: is there a way to measure how close are they to fail?
or they just drop dead unexpectedly?
i dont think so. or i wish they dont.
they shouldnt. should be here to help.
otherwise better not have them.
anyway, whoever knows something or can bring links will be great.
or has questions. i do. a lot.
if not, please dont post. this is a technical matter.
