Rocky,

It really depends on the sensor and how it is set for the application.
These Flood Sensor have 4 small metal gold tabs on the bottom
that when they get wet there is an amount of conductance that happens
between the tabs which is picked up by the internal circuitry and then
sends out a signal.  So for this I would say it is inductance or current
flow that happens.

For some odd reason when the batteries are replaced it does not not talk
to the receiver as before and needs to be re-learned back into the system.
