In Part II, we covered basics ofproximity sensor and hardware implementation details of wake-on-approach proximitysensor. In Part III, we will cover different types of proximity sensor hardwaredesigns ...

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 ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.
