The SFH 7770 digital sensor 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 tell whether the object is moving closer or farther away. Applications
in cell phones and smart phones can be controlled without touching the phone. The
applications open automatically, and the brightness and volume are adjusted at precisely
the right moment. The digital sensor replaces the usual separate ambient light and
proximity sensors and takes up very little space, measuring 2.8 x 2.8 x 0.9 mm.
By combining the two functions, it offers added performance. It consumes 350 μA
during operation and 5 μA in standby mode.
