## Description

This breakout brings ambient light tri-stimulus colour sensing to your project using CIE XYZ plus an IR channel, rather than the more common RGB-style approach. It is designed for applications where you want access to the raw sensor count data so you can match and calibrate it to your own colour space workflow.The sensing channels are centred at 437nm (X1), 574nm (X2), 537nm (Y) and 434nm (Z), and the expectation is that you will calibrate the readings against a known colour space analyser for your application. Adafruit notes that if you want a sensor that directly outputs CIE and lux data, the OPT4048 is a more complete option; this board is better suited to projects that need the underlying XYZ+IR readings.To make integration easier, Adafruit has mounted the TCS34303 on a breakout PCB with support circuitry for both 3.3V and 5V logic levels. It communicates over I2C, so wiring is simple, and the board includes SparkFun qwiic-compatible STEMMA QT connectors for solderless connection to compatible systems. CircuitPython/Python and Arduino drivers are available, making it quick to start reading XYZ+IR data with boards such as Feather, Raspberry Pi, Arduino and Metro328.A QT cable is not included, so you will need to supply your own if you want to use the onboard STEMMA QT/qwiic connectors.

**Product Type:** Colour Sensor
