I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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 ...

Non-contact proximity sensors can improve the ruggedness of manufacturing operations, such as metal component assembly, by replacing delicate mechanical switches. Sensor selection for these ...
