E909-05 Datasheet PDF - ELMOS Semiconductor AG

General Description
The HALIOS® multi purpose optical sensor is based on an optical bridge which provides a contactless detection of gestures (e.g. movement of a finger). The IC E909.05 processes data from optical reflections of an object in front of the sensor using a system called HALIOS® (High Ambient Light Independent Optical System). HALIOS® is highly efficient suppressing ambient light and also has an inherent self calibration capability to eliminate disturbances caused by housing reflections such as dirt or scratches.
