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.

Features:

  • Small CHIPLED package
  • I²C bus interface:
    100 kbit/s; 400 kbit/s; 1.0 Mbit/s and 3.4 Mbit/s
  • Measurement modes programmable
    (STAND-BY, TRIGGERED, FREE-RUNNING)
  • Very low power consumption and stand-by mode

Ambient Light Sensor:

  • Closely matches the sensitivity of the human eye
  • High accuracy from 0.03 – 65,000 lx
  • Low temperature coefficient of photosensitivity
  • Insensitivity to 50-60 Hz flickering
  • Excellent linearity

Proximity Sensor:

  • Standard detection range up to 200 mm, extendable through external driver
  • Gesture recognition function
  • Capable of driving a maximum of 3 LEDs with up to 200 mA
  • Optimized for 850 nm emitters
  • Insensitive to ambient light

Recommended Emitters:

  • Mini MIDLED: SFH 4451
