Hi,
I'm looking for advice or anecdotes from people who've used cap sensors in water/marine environments. I'm not talking underwater, but where there will be splashes, salt crusting and drops of water about the sensing surface.

Are the sensors usable in these environments? Is there any design recommendations to the sensor PCB design to make them workable?

Is it true that completely dry salt crusts are invisible to capacitive-touch sensors?
