Data Sheet: APDS-9950: Digital Light and Proximity Sensor

The APDS-9950 is a digital RGB, ambient light and proximity sensor device in a single 8-pin package.  

The device has an I2C compatible interface providing red, green, blue, clear (RGBC) and proximity sensing with IR LED. The RGB and ambient light sensing feature detects light intensity under various lighting conditions and through various attentuation materials including darkened glass. In addition, the integrated UV-IR blocking filter enables accurate ambient light and correlated color temperature sensing. The proximity feature is factory-trimmed and calibrated to 100mm proximity detection distance without requiring customer calibrations. The addition of micro-optics lenses within the module provides high efficient transmission and reception of infrared energy. An internal state machine allows the device to be put into a low power state between RGBC and proximity measurements providing very low power consumption.
