Do Water sensors Rust? I'm new to Arduino and still learning the basics.
I tried reading water level by using this sensor I left it in the water for about 5 minutes then I noticed it changing color (some parts darker than other)like the water is still over it .
So my question is do Water sensors really rust ? or is it my own imagination?
Most metals will tarnish, rust, or corrode when left in water, especially in the presence of an electric current. To be safe, a water sensor should either be gold-plated or made of a conductive, insoluble, non-metallic substance.
