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 ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

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 ...

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 ...

Driver-monitoring systems (DMS) are becoming common in modern automobiles. Infrared (IR) cameras, utilizing an IR-LED in combination with a photo sensor, help recognize the hazardous microsleep that ...

LED chip maker Taiwan-Asia Semiconductor (TAS, renamed from Opto Tech) is the exclusive supplier of short-wave infrared (IR) LED devices used in the body temperature sensor of Apple Watch 8, according ...

Apple's new Siri personal assistant feature on the iPhone 4S includes a "raise to speak" feature that allows Siri to be activated whenever an active iPhone is raised to the user's ear. The device is ...

LED chip packaging house Bright Led Electronics has landed orders for one billion infrared LED sensor modules worth NT$2 billion (US$66.7 million) through a China-based maker of LED whiteboards, with ...
