The SparkFun Qwiic Tristimulus Color Sensor is built around the OPT4048 High-Speed, High-Precision Tristimulus XYZ Color Sensor from Texas Instruments. This Sensor features a single-chip high-resolution color sensor capable of measuring four channels, each with specific engineered spectral responses. This Standard-sized breakout board has two I2C Qwiic connectors to make interfacing with the OPT4048 easier. It’s part of SparkFun’s Qwiic connect system, so you won’t have to do any soldering to figure out how things are oriented. However, we still have broken out 0.1in.-spaced pins if you prefer to use a breadboard.

Three of the four channels on the OPT4048DTSR closely match the CIE tristimulus spectra, with the fourth channel having a wide-band spectral response. With measurements from these channels, essential 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. This aids in applications where measuring the precise characteristics of the lighting environment is critical, like display brightness, color temperature adjustment, camera color temperature correction, object true color recognition, & medical applications.

We've written an Arduino library to make reading the various measurements easy. It can be downloaded through the Arduino Library manager: search for 'SparkFun OPT4048', or it can be found in the Documents tab.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
