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\/cm\u003csup\u003e2\u003c\/sup\u003e 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.\u003c\/p\u003e \u003cp\u003eThe SparkFun Triad Spectroscopy Sensor communicates over I\u003csup\u003e2\u003c\/sup\u003eC 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 I\u003csup\u003e2\u003c\/sup\u003eC interface. In addition, the Triad can be setup to communicate over serial. The serial interface uses an AT command set.\u003c\/p\u003e \u003cp\u003eWhat 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!\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The I\u003csup\u003e2\u003c\/sup\u003eC address of the AS7265x is 0x49 and is hardware defined. A multiplexer\/Mux is required to communicate to multiple AS7265x sensors on a single bus.
