This high-precision tristimulus color sensor module from 7Semi integrates the OPT4048 by Texas Instruments for professional-grade ambient color detection. The sensor outputs calibratedCIE 1931 XYZ tristimulus values, correlated color temperature (CCT), and ambient illuminance (lux), with strong infrared rejection.
Designed for display calibration, ambient light sensing, and color-critical automation systems, this breakout board supports a3.3V IC interfaceand is compatible with microcontrollers likeESP32,Arduino, andSTM32. The 4-channel detection provides industry-leading2.15 mlux resolutionand up to144 klux dynamic rangeideal for accurate color measurement in a variety of lighting environments.
