Spectral Sensor Breakout - AS7263 NIR (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 AS7263 spectrometer detects wavelengths in the near infrared (NIR) range at 610, 680, 730, 760, 810 and 860nm of light, each with 20nm 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 AS7263 applications include product authentication, bank note/document validation, chemical analysis and food/beverage safety.
