a on Description
The TCS3471 family of devices provides red, green, blue, and clear light sensing (RGBC) that detects light
c _{intensity under a variety of lighting conditions and through a variety of attenuation materials. An internal state}
l ^{machine provides the ability to put the device into a low power mode in between RGBC measurements providing}
very low average power consumption.
a _{The TCS3471 is directly useful in lighting conditions containing minimal IR content such as LED RGB backlight}
ic ^{control, reflected LED color sampler, or fluorescent light color temperature detector. With the addition of an IR}
blocking filter, the device is an excellent ambient light sensor, color temperature monitor, and general purpose
Techn ^{color sensor.}
