AS7263 Module (GY-AS7263)

🔹 AS7263 Module (GY-AS7263) – 6-Channel Near-Infrared Spectral Sensor

The AS7263 is a digital 6-channel spectrometer designed for spectral identification in the near-infrared (NIR) range. It detects light at six specific wavelengths (610nm, 680nm, 730nm, 760nm, 810nm, and 860nm), each with a 20nm full-width half-max (FWHM) bandwidth. This makes it ideal for material analysis, product authentication, and chemical sensing applications.
