일반 설명

The TSL2772 device family provides both ambient light sensing (ALS) and, when coupled with an external IR LED, proximity detection. The device family is based on the TAOS patented dual-diode technology that enables accurate ALS results and approximates human eye response to light intensity under a variety of lighting conditions.
