Hi
I have two metal plates. One is rotating, and the other is static. I want to detect the moving plate whenever it passes over the static one. The distance between them is about 1" (2.5cm).
I can put any electronic components on the static plate, but I can't have anything electronic on the moving one.
I am not sure how to approach it, any idea will help.
Thanks in advance.
