Why? That ARM based devices have, if I am not mistaken, ADCs and GPIOs
on board. It's a matter of good analog front-end extension and ARM
code to catch the signal, digitize it and send it to the database.
Professional multimeters could be designed this way in the future. The
multi core 1GHz+ devices (not necessarily ARMs) can be quite capable
as pro EE devices, say, oscilloscopes. I'd rather say it's impressing,
not depressing.
