AS7341 Visible Spectrum Infrared Color Spectrometer Sensor Module User Manual

تعارف

The AS7341 is an advanced 11-channel multi-spectral sensor designed for precise color detection and spectral analysis. It offers a broad spectral response from approximately 350nm to 1000nm, making it suitable for a wide range of applications including color matching, skin tone measurement, laboratory analysis, and ambient spectral sensing.

This module features 8 optical channels covering the visible spectrum, a dedicated near-infrared (NIR) channel, and a clear photodiode channel. Additionally, it integrates a flicker detection engine for 50Hz or 60Hz ambient light flicker. With 6 parallel ADCs, the AS7341 ensures fast and accurate measurements.
