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 ...

Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively ...

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 ...
