First off, thanks for the tip!
I went to craft store and got some of this…
Is that about right?
Then, to use it, do I connect one each to the terminals, and then twist the pieces together so that if either one gets wet, it will soak through to the other one to make the connection, or just tape them closely together?
Once that part is figured out, do I just lay it out around where water would go if there is a leak (sort of like the leak detector that comes with the Rheem EcoNet WiFi Module)?
If so, do you have any idea what the length limit should be?
The reason I ask is that, if I could string a few of them together like this, I could have one sensor for two sinks in the bathroom…they’re a couple feet apart, and I would need to have the total length be probably three wires long.
