일반 설명
TSL2572 device family 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. Accurate ALS measurements are the result of TAOS’ patented dual-diode technology and the UV rejection filter incorporated in the package. The operating range can be extended to 60000 LUX when the low-gain mode is use. The TSL2572 device is particularly useful for enabling automatic brightness control (ABC) in large LCD flat-panel TVs and displays by providing optimum viewing in diverse lighting conditions (daytime versus nighttime viewing) while significantly reducing energy consumption to meet the stringent ENERGY STAR requirements.

Evaluation Kit for TSL2572
TSL2572EvalKit
The TSL2572 evaluation kit comes with everything needed to evaluate the TSL2572 Ambient Light sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with a USB cable), a TSL2572 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 TSL2572 I2C digital outputs to calculate ALS illuminance in lux approximating the human eye response.
