A while back, I was reading a thread where a user made a custom Is-Raining sensor from a Leaf Wetness sensor, using, among other things, a light bulb I believe. It was one of those "this is interesting" moments, but then I forgot about it and didn't bookmark the page. So no idea who it was or even if it was on this forum or not (but I think it was). Anyway, as the title says, I want to try and make an is raining sensor using Davis' leaf wetness sensor. Ideas?
