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 ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

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 ...

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 ...

Vertically-integrated LED maker Opto Tech has received many rush orders for infrared (IR) LED and UV-C LED devices as well as Si-based sensor chips arising from the coronavirus pandemic, with the ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...
