Light sensors have all sorts of practical uses in the modern era, most notably in devices with auto-brightness for their screens and in digital cameras to adjust exposure. With the Ambient Light Sensor Breakout, it's be a breeze to interface with the TEMT6000 Light Sensor so you can bring the ability to detect light levels to any project.
As the name suggests, the TEMT6000 Light Sensor will detect the brightness of its surroundings. While there are many properties of light that can help us categorize its brightness, the TEMT6000 measures illuminance (measured in lux (lx), often denoted Ev). Don't worry if illuminance is new to you though, the TEMT6000 is very intuitive to use: brighter = more current, darker = less current.
