OSRAM – Intelligent Proximity Sensing with Gesture Recognition SFH 7770 E6

The SFH 7770 E6 from OSRAM Opto Semiconductors combines the functions of a digital ambient light sensor with those of a digital proximity sensor. It determines the ambient brightness, detects the presence of an object nearby and can even tell whether the object is moving closer or moving further away. By using 2 or 3 IR LEDs instead of one, it is even possible to detect gestures.
