## Overview

The SparkFun Triad Spectroscopy Sensor combines three AS7265x sensors to analyze 18 distinct light frequencies spanning UV to IR. Featuring flexible I2C and serial communication, integrated UV, white, and IR LEDs with software control, and Qwiic compatibility for solderless integration, it delivers precise, portable spectral analysis ideal for advanced material testing and prototyping.

## Description

The SparkFun Triad Spectroscopy Sensor is a powerful optical inspection sensor. Three AS7265x spectral sensors are combined alongside a visible, UV, and IR LEDs to illuminate and test various surfaces for light spectroscopy. The Triad is made up of three sensors; the AS72651, the AS72652, and the AS72653 and can detect the light from 410nm (UV) to 940nm (IR). In addition, 18 individual light frequencies can be measured with precision down to 28.6 nW/cm2 and accuracy of +/-12%. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.The SparkFun Triad Spectroscopy Sensor communicates over I2C by default or over 115200bps serial. We’ve written a fully formed library to be used with the Arduino IDE platorm to access all the various features include taking readings and illuminating LEDs all over the Qwiic I2C interface. In addition, the Triad can be setup to communicate over serial. The serial interface uses an AT command set.What can you do with light spectroscopy? It’s an amazing field of study, and the SparkFun Triad brings what used to be prohibitively expensive equipment to the desktop. The AS7265x should not be confused with highly complex photon spectrometers, but the sensor array does give the user the ability to measure and characterize how different materials absorb and reflect 18 different frequencies of light. We’ve also written a full library to be used with the Arduino IDE platform that makes reading and interacting with the Triad simple and easy!The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

## Questions & Answers

**Q: How far are the detectors @ their most effective and distance to worst effective?**
A: Hello!

Unfortunately, this has not been tested by SparkFun.  You would want to run some experiments to determine the worst and most effective distances.  The Data sheet might have some useful info, but will need to test in your specific set up.  Also, the optional PTH LED's would change the effective distances.
