The OPT4048 is a single-chip high resolution color sensor, capable of measuring four channels each with specific engineered spectral responses. Three of the four channels closely match the CIE tristimulus spectra with the fourth channel having a wide band spectral response. With measurements from these channels, important characteristics of the lighting environment can be extracted like (i) light intensity (lux), (ii) color in CIE XY, LUV coordinates and (iii) Correlated Color Temperature. The OPT4048 is available in a small SOT-5X3 package.
