In need a sensor that looks upside down at a metal part.
The metal part is at a distance from 100mm to 250mm from the sensor. The whole construction is located outside, so it has to be resistant to water that can rest on the surface of the
sensor that looks upside (it may not detect water or possible dirt on the sensor).
Inductive sensors probably don"t have those large ranges and photocells may probably detect water as an object.
Has someone experience with detection in these conditions?
What sensor should you advise?
