Introduction

The SparkFun Triad Spectroscopy Sensor is a powerful optical inspection sensor. Three AS7265x sensors are combined alongside a visible, UV, and IR LEDs to illuminate and test various surfaces for light spectroscopy.

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 mass 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.

Required Materials

To follow along with this hookup guide, you will need one of the following Qwiic shields with an Arduino. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.

Note: If you are looking to reduce the cost and avoid soldering headers to the Qwiic shield, try taking a look at the RedBoard Qwiic. It is essentially a RedBoard with Qwiic connector.
