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 ...

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

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 ...

Scientists have discovered the function of a third type of light sensor in the eye -- not vision, but control of the body’s internal clock -- opening a new pathway for potential treatments of ...

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 ...

Advancements in environmental sensing have played an important role in smart factories, automobiles, medical wearables and other end equipment in which electrification is becoming more common. In ...

(Nanowerk News) To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from Nanyang Technological University, Singapore (NTU Singapore) ...
