Re: Newbie - water detector circuit help please

Yeah Just wet vs dry is enough for me - mearly knowing that water has
been present since I last checked is enough to tell me there is a
problem that I'll need to call the plumber back for.

As water's not pouring out I'm in favor of an LED warninfg rather than
buzzer as being woken at 2 in the morning wouldnt be appreciated by the
girlfriend ;-)

Having said all that I'm looking at this as a learning excercise as
well and like the thought of damp detection with wire grids/blotter
paper - would it be a massive undertaking to do an LED scale (say 1-5)
measuring how damp it had been?
(i.e. if it is just damp 1 LED lights, under water = all 5 light with
the display "locking" at the highest level recorded since last reset? -
this is beyond what I need to do but if still fairly straightforward
would be more fun!)

Thanks again for your help!
