Spectroscopy Sensor Module Covering the Wavelength Range from 410nm to 940nm - AS7265x (Qwiic) AS72651 AS72652 AS72653

The AS7265x series integrates three chips to provide an 18-channel multispectral sensor array covering a wavelength range from 410nm to 940nm. AS72651 covers the near-infrared wavelength range from 600nm to 870nm and acts as the master controller for the entire assembly. When used in conjunction with AS72652 (with a spectral response from 560nm to 940nm) and AS72653 (with a spectral response from 410nm to 535nm), the complete system offers 18 channels with a 20nm Full Width at Half Maximum (FWHM).

Advantages:

Detection of spectral fingerprints in visible and near-infrared spectra.

On-chip signal processing, reducing hardware costs.

Sample illumination without the need for external LED drivers.

Easy connectivity to mobile devices or external microcontrollers.

Simplified sensor communication from a host perspective, requiring only one client.
