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). The SparkFun Triad Spectroscopy Sensor is a powerful optical inspection sensor also known as a spectrophotometer. The SparkFun Triad Spectroscopy Sensor communicates over I2C by default or over 115200bps serial.
