Proximity sensing based on infrared signal acquisition and processing typically requires two parts to form the optical front end: an infrared LED and an optical sensor. The infrared LED beams infrared ...

The capacitive sensing user interface has established itself in recent years as a practical and innovative upgrade for push buttons in many types of consumer goods. A light tap on a smooth surface or ...

[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 ...

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 ...

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 ...

Time-of-flight (ToF) sensors open up new application areas and use cases for proximity sensing and presence detection technologies, and these sensors can add valuable functionalities and intelligence ...
