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 ...

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 ...

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 ...

Urban mobility problems demand clarity. Intersections remain the most common sites for crashes, congestion, and violations.

ALSs (ambient-light sensors) have been around for years, but they are now seeing increased use due to the success of smartphones, such as Apple’s iPhone. The iPhone uses an ALS to reduce power demands ...
