Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a “floating input”, but unfortunately it is very ...

It seems like engineering 101, but do you actually remember the specific differences between inductive proximity, inductive displacement, and eddy-current sensors? I asked a few friends and everyone ...
