Spectral Sensor Breakout - AS7262 Visible (Qwiic) (SEN-14347)

DESCRIPTION

The AS7262 Visible Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterise how different materials absorb and reflect different wavelengths of light. The AS7262 Breakout is unique in its ability to communicate by both an I²C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board‚Äö simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic Shields, then stack the board on a development board. You'll be ready to upload a sketch to start taking spectroscopy measurements in no time.

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.
