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 ...

This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact ...

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 ...

Most design engineers of consumer and industrial products always look for various ways to achieve their desired goals in applications ranging from wearables to handheld devices to industrial ...

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 ...

Proximity sensors have been around on our phones for quite a while and apart from detecting the presence of a human ear, it also locks the screen when the phone’s in the pocket and enables gesture ...

The IR proximity sensor enables wireless earbud in-and-out of ear detection to help extend battery life between charging and can be used in tandem with another TMD2635 to enable elementary touchless ...

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 ...

It is critically important for instrument users to understand what the sensors in their instrument cannot properly measure, as well as what they can. Non-dispersive infrared (NDIR) sensors are ...
