TCS37717 Color Sensor

Color light-to-digital converter with proximity sensing, I²C = 1.8V

 

The TCS3771 family of devices provides red, green, blue, and clear (RGBC) light sensing and proximity detection (when coupled with an external IR LED). They detect light intensity under a variety of lighting conditions and through a variety of attenuation materials. The proximity detection feature allows a large dynamic range of operation for use in short distance detection behind dark glass such as in a cell phone or for longer distance measurements for applications such as presence detection for monitors or laptops. The programmable proximity detection enables continuous measurements across the entire range. In addition, an internal state machine provides the ability to put the device into a low power mode in between RGBC and proximity measurements providing very low average power consumption.  This data is transferred via an I2C to the host.
