Spectral Sensor Breakout - AS7262 Visible (Qwiic)

With a spectrometer you can reveal the composition of an object. The SparkFun Spectral Sensor Breakout boards bring spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The boards are unique as they can communicate by both an I2C interface and serial interface using AT commands.

The AS7262 and AS7263 spectral sensors from the Austrian-based company ams AG are now available on breakout board.

The AS7262 spectrometer detects wavelengths in the visible range at 450, 500, 550, 570, 600 and 650nm of light each with 40nm of full-width half-max detection. The board also has multiple ways for you to illuminate objects that you will try to measure for a more accurate spectroscopy reading. There is an onboard LED that has been picked out specifically for this task, as well as two pins to solder your own LED into.

The AS7262 applications include portable spectrometry, horticulture, color matching/identification, precision color tuning/calibration, authentication and brand protection.
