Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light ...

Infrared sensors that detect the short-wave infrared (SWIR) region can clearly recognize objects not only during the day and ...

A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped ...

SPOKANE, Wash. — The City of Spokane is launching a program offering property owners a free solar-powered, motion-detecting residential light. The Spokane Safe and Bright Residential Light program ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, ...

You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

If you’ve ever stumbled through a dark kitchen at midnight or struggled to find something in a shadowy closet, the MCGOR 10-inch Under Cabinet Lighting 2-Pack is about to become your new best friend.

A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...

Most modern cars have tire pressure monitoring systems (TPMS), which will alert you if your tires need air. While most of the readings they give are accurate, they can still fail like any other part ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...
