This Series is integrates an optical proximity sensor and digital
ambient light sensor (ALS) on a single chip. The proximity sensor
can detect objects 1cm to 10cm away, making touchless motion
possible. Simply wave an object, such as a hand, above the sensor
to initiate various operations (e.g. scroll). The ALS features a
wide detection range, from darkness to direct sunlight, allowing
adjustment of the brightness of the LCD and keypad in mobile phones
and portable devices to match ambient conditions for optimum
visibility with minimal power consumption.
