I have a project that I'd like to do which would basically just alert me if water is detected. We have a basement location and with some storms, water creeps in when no there, which is a bad thing. I've searched this forum as well as the internet without much luck on what type of sensor would be used for something like this. Something I could run the wire next to the door, and just stick it in a corner location, so when water came in, it would immediately detect the moisture.
Electronics newbie here so forgive me if this is a super simple question. One thing to note there are small children in the area so I'd like to have something that's clean and protected.
