SparkFun Triad Spectroscopy Sensor - AS7265x Spectral Sensor Module
The SparkFun Triad Spectroscopy Sensor (AS7265x) is a compact spectral analysis module compatible with 3.3V systems like Arduino and Raspberry Pi via I2C or serial interface, enabling precise measurement of 18 distinct light wavelengths from 410nm to 940nm.
Features
- Triple AS7265x sensor array for 18-channel spectral sensing from UV (410nm) to IR (940nm).
- Selectable I2C (default) or 115200 bps serial communication interface for flexible system integration.
- Integrated illumination LEDs: 405nm UV, 5700K white, and 875nm IR for controlled sample lighting.
- High sensitivity with a resolution of 28.6 nW/cm² per count and typical accuracy of ±12%.
- Qwiic connector enables solderless connection, with 0.1″-spaced breakout pins for breadboard prototyping.

The SparkFun Triad Spectroscopy Sensor integrates three specialized ams OSRAM AS7265x spectral sensors (AS72651, AS72652, AS72653) into a single module, functioning as a compact spectrophotometer. It operates on the principle of filtered photodiode arrays, where each of the 18 channels is tuned to a specific narrowband wavelength, allowing for the characterization of light absorption and reflection properties of materials.
Communication is handled via a selectable I2C or UART serial interface (115200 bps), with an onboard level shifter ensuring 3.3V logic compatibility. The module includes software-controllable integrated LEDs (UV, white, IR) for active illumination, and features dedicated pins for optional external light source control. Pre-programmed with the latest ams OSRAM firmware, it is supported by a comprehensive Arduino library for simplified data acquisition and LED management.
