I travel a lot and my upstairs neighbors have a shower that leaks onto my dinner table :-( When i'm present i can go upstairs and tell them to fix it. But when i'm gone :-(
so i was thinking of making a water drop detection (please tell what sensor do use) and then sending me and the upstairs neighbor that it is leaking.
please tell me detailled which components i need to achief this.
thanks a lot
