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

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

IKEA has launched its new Gömpyssling LED light with sensor. It's a motion-activated light which automatically switches on when you open a cupboard or step into a space, then turns itself off after ...

This post is brought to you in paid partnership with AUVON. They plug directly into your outlets, add a warm backlit glow, and automatically adjust to your environment so you’re not wasting energy or ...

Stratio, a Korean deep-tech startup founded by three Stanford Ph.D. graduates, is introducing what it claims is the first germanium-based short-wave infrared sensor designed for large-scale commercial ...

The Dallas Cowboys have placed Trevon Diggs on injured reserve as the star cornerback works through concussion and knee injuries, the team announced ahead of their Week 8 game against the Denver ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

High-end consumer drone producer DJI has announced the release of its Mini 5 Pro. Not only does it claim to be the world's first palm-sized drone with a one-inch image sensor, but it's got a few other ...

This project implements a smart traffic signal system using Arduino UNO, ultrasonic distance sensors, and LED signals. The system controls traffic signals at a junction by dynamically adjusting the ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

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 ...
