Ambient Light Sensors & Proximity Detection

Ambient Light Sensors & Proximity Detection

ams supplies a family of products which combine an Ambient Light Sensor (ALS) and proximity detection in a single device. The ALS provides measurements of ambient light intensity which match the human eye’s response to light under a variety of lighting conditions, and through a variety of attenuation materials. The proximity detection feature allows a large dynamic range of operation for use over short distances and behind dark glass. These devices are intended for use in mobile phones, and over longer distances for presence detection in computer displays and monitors.
