[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Designing with high-fidelity capacitive proximity sensors requires careful consideration of mechanical design, sensor placement/design, and end-application operating environments. Careful evaluation ...

Proximity detection adds many smart features to the devices we use.For example, when making a call with a phone held to your ear, face detection using proximity sensing can disable the touchscreen and ...

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 ...
