As electronics seamlessly weave their way into our lives, sensors play an increasingly important role. Light sensors are among the simplest and cheapest sensors, allowing their inclusion into numerous ...

With the TSL2550 sensor, the intensity of ambient light can be converted to digital signals that, in turn, can be used to control the backlighting of display screens found in portable equipment, such ...

This post sponsored by Texas Instruments. The OPT3001 sensor accurately measures the intensity of light visible to the human eye regardless of light source. Its precision spectral response tightly ...

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 ...

The ambient light sensor on your Dell business laptop adjusts the brightness of your screen according to light intensity picked up from the room. In a brightly lit office, the ALS increases the ...

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

Jay Holben During one of my recent lectures, there was a great deal of confusion about how to adjust light intensity and when does light quality and/or color change when altering the intensity.
