General Description
The TCS3471 family of devices provides red, green, blue, and clear light sensing (RGBC) that detects light intensity under a variety of lighting conditions and through a variety of attenuation materials. An internal state machine provides the ability to put the device into a low power mode in between RGBC measurements providing very low average power consumption. This data is transferred via an I2C to the host.
This product suits for the following applications:
- Light color temperature measurement
- RGB LED backlight control
- RGB LED consistency control
- Health fitness
- Industrial process control
- Medical diagnostic equipment

The TCS3471 Evaluation Kit comes with everything needed to evaluate the TCS3471 color sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with an USB cable), a TCS3471 daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the color sensor settings as the PIC takes the TCS3471 I2C digital outputs to calculate illuminance in lux and color temperature.
