ESP rain - wall sensor

Simple rain sensor, to be used with the regular moisture sensor. I found out that setting the threshold to 0.67V for detected rain works fine for me, but you mileage might vary There is some extra space on the right. You can add more stuff there. For example I have a old gate remote control that the esp can trigger to open my gate. But you can be creative. You can add some relays or whatnot :) I tested it under heavy heavy rain and it did not budge. Also it in direct sun for some hours during the summer and again never got a problem. It is supposed to be waterproof, there is a space at the bottom for an LED. if you do not need it just seal it up :) Also remember to put a little bit of silicon in the groove. So it makes it more water resistant. I forgot to put the silicon and still had no water. But please remember it
