OK ... went to MAPLIN web site they do sell a Velleman water detector kit,
which is totally useless ... it has a simple 2 copper wire detector ... when
it's wet it switches a single transistor to sound a buzzer ....
It will keep sounding untill it dries, which in UK Summer means battery will
not last very long.



Come on guys somebody must know of a better sensor ?


Now if sombdoy knew how to get a car water detector working that may be a
good plan ... I have a glass roof to kitched & conservatory so plenty of
places to put it.
