+# Adafruit OPT4048 Library [![Build Status](https://github.com/adafruit/Adafruit_OPT4048/workflows/Arduino%20Library%20CI/badge.svg)](https://github.com/adafruit/Adafruit_OPT4048/actions)[![Documentation](https://github.com/adafruit/ci-arduino/blob/master/assets/doxygen_badge.svg)](http://adafruit.github.io/Adafruit_OPT4048/html/index.html)
+
+This is an Arduino library for the Adafruit OPT4048 breakout board, a high-speed, high-precision tristimulus XYZ color sensor.
+
+## About the OPT4048
+
+The [OPT4048](https://www.adafruit.com/products/6334) is a high-precision, tristimulus XYZ color sensor that provides accurate color measurements by using an integrated CIE1931 XYZ filter technology. 
+
+Key features:
+* Four-channel sensor (X, Y, Z, clear)
+* High-precision color measurements with CIE1931 filter technology
+* Wide dynamic range with auto-ranging capability
+* Programmable interrupt with high and low thresholds
+* Adjustable conversion time (600μs to 800ms per channel)
+* Measures color temperature, illuminance, and chromaticity
+* I²C interface
+* 1.7V to 3.6V operating voltage
+
+## Dependencies
+
+This library depends on the [Adafruit BusIO](https://github.com/adafruit/Adafruit_BusIO) library for I²C communication.
+
+## Installation
+
+You can install this library through the Arduino Library Manager. Search for "Adafruit OPT4048" and install the latest version.
+
+To manually install:
+1. Download the .zip file from GitHub
+2. In the Arduino IDE: Sketch -> Include Library -> Add .ZIP Library
+
+## Hardware
+
+* [Adafruit OPT4048 - High Speed Tristimulus XYZ Color Sensor Breakout](https://www.adafruit.com/products/6334)
+
+## Examples
+
+The library includes several examples demonstrating various features:
+
+* **opt4048_basictest**: Basic usage with continuous readings
+* **opt4048_fulltest**: Demonstrates all sensor configurations
+* **opt4048_intpin**: Using the interrupt pin for data-ready notifications
+* **opt4048_oneshot**: One-shot measurement mode for low power applications
+
+## Library Features
+
+* Initialize the sensor with custom I²C address and Wire interface
+* Configure measurement settings (range, conversion time, operating mode)
+* Set up and use the interrupt system
+* Read raw channel data from all four sensors
+* Calculate CIE color coordinates (x, y) and illuminance (lux)
+* Determine color temperature in Kelvin
+
+## Documentation
+
+For more information on using this library, check out the [examples](/examples) folder.
+
+Full documentation of the OPT4048 sensor can be found in the [datasheet](https://www.ti.com/lit/ds/symlink/opt4048.pdf).
