These devices detect light intensity under a variety of lighting conditions and through a variety of attenuation materials, including dark glass. The proximity detection feature allows a large dynamic range of operation for accurate short distance detection, such as in a cell phone, for detecting when the user positions the phone close to their ear. An internal state machine provides the ability to put the device into a low power state in between proximity and RGBC measurements providing very low average power consumption. The color sensing feature is useful in applications such as LED RGB backlight control, solid state lighting, reflected LED color sampler, or fluorescent light color temperature detection. With the addition of an IR blocking filter, the device is an excellent ambient light sensor, color temperature monitor, and general purpose color sensor.
