The Sparkfun Triad Spectroscopy Sensor is a powerful optical inspection sensor, also known as a spectrophotometer. Three AS7265x spectral sensors are combined with a visible, UV and IR LED to illuminate and test different surfaces for light spectroscopy. The triad consists 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 a precision of up to 28.6 NW/cm2 and an accuracy of +/-12%. By using our convenient Qwiic system, no soldering is required to connect it to the rest of your system. However, if you prefer to use a breadboard, we have broken out 0.1" intermediate pins.
The Sparkfun Triad spectroscopy sensor communicates serially via I2C or via 115200bps. We have written a fully-trained Arduino library to access the various functions, including recording readings and lighting LEDs across the Qwiic I2C interface. In addition, the triad can be set up for serial communication. The serial interface uses an AT command set.
