If you are wandering to make a device that is used to identify the spectral composition of light. Then this Sensor is needed for can buy this Spectroscopy sensor From at a reasonable price.

The SparkFun Triad Spectroscopy Sensor is a powerful optical inspection sensor also known as a spectrophotometer. Three AS7265x spectral sensors are combined alongside 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 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 an 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 Arduino library to access all the various features include taking readings and illuminating LEDs all over the Qwiic I2C interface. In addition, the Triad can be set up 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 Arduino library that makes reading and interacting with the Triad simple and easy!
