Spectral Triad (AS7265x) Hookup Guide
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.
AMS has combined the power of three sensors to cover the measurement of light from 410nm to 940nm in 18 individual bands.
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.
You will also need a Qwiic cable to connect the shield to your AS726X, choose a length that suits your needs.
Qwiic Cable - 50mm
PRT-14426Qwiic Cable - 200mm
PRT-14428Qwiic Cable - 500mm
