ams TSL27721 Ambient Light Sensor

×

Description

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.

Details

Features
