IR (infrared)-proximity sensors can sense the presence of an object, its distance from a reference, or both. Applications include speed detection, sensing of the hand in automatic faucets, automatic ...

Vishay’s VCNL4100 is an IR proximity sensor that works up to 1m, and includes an ambient light sensor. Inside, it combines an infra-red (940nm) emitter, photo detectors for proximity and ambient light ...

If it's just a sensor, why would it be important? That's a good question, but with proximity sensors being used so heavily in smartphones these days, and that iPhone proximity problem that caused so ...

An Apple patent application published by the U.S. Patent and Trademark Office on Thursday describes a system that may one day replace the infrared proximity sensors deployed in current iPhones with ...
