General description
The TSL2571 family of devices provides ambient light sensing (ALS) that approximates human eye response to light intensity under a variety of lighting conditions and through a variety of attenuation materials. While useful for general purpose light sensing, the device is particularly useful for display management with the purpose of extending battery life and providing optimum viewing in diverse lighting conditions. Display panel and keyboard backlighting can account for up to 30 to 40 percent of total platform power. The ALS features are ideal for use in notebook PCs, LCD monitors, flat-panel televisions, and cell phones.
Not Recommended for New Designs!

TSL2571EvalKit
The TSL2571 Evaluation Kit comes with everything needed to evaluate the TSL2571 ambient light sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with an USB cable), a TSL2571 daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the ALS sensor settings as the PIC takes the TSL2571 I2C digital outputs to calculate ALS illuminance in lux approximating the human eye response.
