Yes - I've seen this. I totally understand the principals - but don't get the electronics. This is the bit I need an "Idiots" guide for.

I "Get" that a sensor can detect either reflected 'light' from a silvered numeric on a gas meter, or detect the pulses from a blinking LED on a 'leccy meter - I just don't "Get" the electronics to hook this up to an Idratek module . .
Nobody help with this?
