If you do encounter the device you were talking about, would you let me

I'm at work at the moment, but I'm sure that there's a German company
that make sensors of the kind you are thinking of. Unfortunately
they're not cheap, and as my sparky bought it for me, I'm not sure
they're available retail (but they're good - my leccy only buys the
best). What I will do when I get home is see what the brand name is
and get back to you.
