An ambient light sensor module is a device used to measure the intensity of ambient light in a given environment. It consists of an ambient light sensor, which is a type of photodetector that is sensitive to light in the visible spectrum, and an associated circuit board or module that provides the necessary electrical connections and processing circuitry.

The TEMT6000 ambient light sensor module is a specific type of ambient light sensor module that uses a TEMT6000 sensor, which is a phototransistor-based ambient light sensor that is sensitive to light in the visible spectrum. It is commonly used in a variety of applications, such as display backlighting control, camera exposure control, and ambient light sensing for energy-saving purposes.

The TEMT6000 ambient light sensor module typically includes a connector or interface for connecting to a microcontroller or other device, as well as any necessary processing or control circuitry. It may also include additional features such as a display or user interface for reading and displaying the measured ambient light intensity.

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 E_v). Don’t worry if illuminance is new to you though, the TEMT6000 is very intuitive to use: brighter = more current, darker = less current.
