Problem: I own a home that I'm not always at, It rains there a lot and I need a way to monitor if there is rain by using a sensor so i can turn on a pump to move the water away from my house.
Solution: I'm using a raspberry pi to do all the heavy lifting. So I have a relay along with code that talks to everything. The raspberry pi is the easy part of this. I'm a CS not a EE.
My question: I'm looking for a sensor that will last outside without any maintenance, for up to 6 months. That will sense if it is wet and talk to the raspberry pi. I found a sensor.
That I'm pretty sure i can hack up, but haven't found anything that looks a bit more "long term." For my application, i think im going to really test the hell out of this, if it breaks i would have to monitor my house physically with a web cam to see if its flooding. If i found a sensor thats reliable, i could save time by not worrying about it at all, and letting the sensors + raspberrypi + notifications to do all the "worrying" for me.
