TCS3430
Color and ALS Sensor
General Description The device features advanced digital Ambient Light Sensing
(ALS) and CIE 1931 Tristimulus Color Sensing (XYZ). Each of the
channels has a filter to control its optical response, which allows
the device to accurately measure ambient light and sense color.
These measurements are used to calculate chromaticity,
illuminance and color temperature, all of which are used to
support various potential applications.
Ordering Information and Content Guide appear at end of
datasheet.
