To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists have created a new type of light sensor that is both flexible and highly sensitive.

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...

Ambient light sensors (ALSs) are photodetectors that approximate the human eye’s response to light intensity under a variety of lighting conditions and through different attenuation materials. They’re ...

What are the most common types of light sensors? Two of the most common light sensors are phototransistors and positive-intrinsic-negative (pin) photodiodes. Both generate signals that vary with ...
