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 ...

Take a Si1120 Ir-LED sensor and seven infrared LEDs. Add in one ultra-low power C8051F930 MCU. Mix thouroughly. The result is Silicon Labs' $199 Si1120 Evaluation Kit. It could also be your next 3D ...

Maxim Integrated Products Inc. introduces the MAX44000, a digital ambient-light and infrared proximity sensor that detects light like a human eye. Maxim Integrated Products Inc. introduces the ...

New TMD2635 from ams occupies a volume of just 1mm3 proximity detection triggers help extend longer listening between battery charges PREMSTAETTEN, Austria--(BUSINESS WIRE)-- ams (SIX: AMS), a leading ...

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 ...

Over the last decade or so, we’ve been inundated with appliances with wireless or “smart” technology that is often of dubious utility. No one really needs a tablet in their refrigerator or Wi-Fi on ...

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 ...

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 ...

Circuit sculpture is a great way to elevate your soldering and electronics skills to the realm of three-dimensional art. In this case, art can be practical, too. Take [romaindurocher]’s interactive ...
