Help with rain sensor controlling a pump
Hello. I was wondering what I need to connect a rain sensor to, to activate a sump pump? I'll be irrigating from a tank, and I'd like to connect an ac timer to a rain sensor, so that the sump pump turns on for a timed period; only if it hasn't rained in a while. The garden is 30 mins away by metro and another 30 walk! It's crazy. Sorry I dont have much experience with these things.
