## Description

The SparkFun Tristimulus Color Sensor is built around the Texas Instruments OPT4048DTSR — a high-speed, high-precision four-channel colour sensor. Three channels closely match the CIE 1931 tristimulus XYZ spectra with excellent IR rejection, while a fourth wide-band channel provides broad spectral response. From these measurements, you can extract light intensity (lux), colour coordinates (CIE XY, LUV), and correlated colour temperature (CCT). Two Qwiic connectors and broken-out 0.1″ headers provide flexible I2C connectivity. An Arduino library is available via the Library Manager (search "SparkFun OPT4048"). Key Features OPT4048DTSR Sensor – Four-channel tristimulus colour sensor matching CIE 1931 spectra 26-Bit Dynamic Range – 2.15 mlux to 144 klux with semi-logarithmic output High Precision – 12 configurable conversion times from 600 μs to 800 ms per channel Qwiic / I2C Interface – Two horizontal Qwiic connectors, plus 0.1″ headers Selectable I2C Address – 0x44 (default), 0x45, or 0x46 Ultra-Low Power – 24 μA operating, 2 μA standby Hardware Interrupt – External pin for synchronised triggers Automatic Range Selection – Seven binary logarithmic full-scale ranges with excellent gain matching Specifications Sensor – OPT4048DTSR (Texas Instruments) Channels – 4 (XYZ tristimulus + wide-band) Dynamic Range – 2.15 mlux to 144 klux Supply Voltage – 1.71–3.6 V Operating Current – 24 μA (2 μA standby) I2C Address – 0x44 (default), 0x45, 0x46 Board Size – 1″ × 1″ (standard SparkFun footprint) Operating Temperature – -40°C to +85°C Ideal For Display brightness and colour temperature adjustment Camera colour temperature correction True colour recognition and sorting Ambient light measurement and lux sensing Medical and scientific colour analysis Package Contents 1× SparkFun Tristimulus Color Sensor – OPT4048DTSR (Qwiic) Resources Hookup Guide OPT4048 Datasheet (PDF) Schematic (PDF) Arduino Library (GitHub) Hardware Design Files (GitHub)
