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 ...

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 ...

Maxim Integrated Products Inc. introduces the MAX44000, a digital ambient-light and infrared proximity sensor that detects light like a human eye. Designed using the company's proprietary BiCMOS ...

Every robotics project out there, it seems, needs a way to detect if it’s smashing into a wall repeatedly, acting like the brainless automaton it actually is. The Roomba has wall sensors, just about ...

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 ...

We present a novel multi-modal tactile sensor which consists of an infrared proximity sensor and a barometric pressure sensor embedded in an elastomer layer with potential use in prosthetic devices.
