I have been using the moisture probes with the coated circuit boards outside for several months this summer.
@DonpK, would you mind posting details of your capacitive moisture probes and experience using them? (In a separate thread would be better i guess.) I have been using the Vegetronix probes for a few years but they only seem to last for 18 months or so in the ground. My initial attempts at a conformal coating have not been very satisfactory, reducing sensitivity considerably and only extending the life expectancy by a small increment. The probes are too expensive to replace that often.
