Gravity: TCS3430 Tristimulus Color Sensor Colour_Yellow and no external resistors areTCS3430 XYZ Tristimulus Color Sensor employs the new generation of TCS3430 spectral sensor IC launched by the well known AMS company. It 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
