the clever method ...
Hi,
I think a fair solution could be to use capacitive detection using the RC oscillator :
The probe being the ... Capacitor.
just compare the duration of, say 256 osc periods to an external RCTime result ...
With water , the capacity of the probe is high ... Osc runs slow ...
When dry, the capacity is low and osc runs faster ...
Interest ??? can even run the 32 Khz clock for power saving, no direct contact of the electrodes and the water ( works with " pure" water also - no corrosion or dirt disturbing measurements )
Some level MEASURES can also be made using the RCTime command, but less power savings ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
