Hi,
Out of curiosity - how do those hand held AC proximity sensors work ?
(e.g. the pen sized devices that you hold near to a live mains wire
which light up when AC is present). Is there an off the shelf IC that
you can purchase to make one yourself ? Anyone have a circuit diagram
for one ?
Reason for asking, I want to build an electronic circuit to detect the
presence of 240v in a wire - without disturbing the wire.
Many thanks,
Tim.
