AS7341 AS7343 Visible spectrum infrared color spectrometer sensor module
AS7341 / AS7343 Spectrometer Sensor Module is a compact multi-channel spectral sensor capable of detecting visible and near-infrared light across multiple bands. Ideal for color analysis, light quality detection, environmental sensing, and portable spectrometry applications.
The AS7341 and AS7343 are highly integrated spectrometer sensors developed by AMS, designed for precise light and color analysis in the visible (VIS) and near-infrared (NIR) ranges. These sensors integrate multiple spectral channels into a single compact module and are used in applications ranging from color calibration, light source analysis, agriculture, and portable optical instruments to healthcare and wearables.
The modules communicate via I²C, making them easy to integrate with Arduino, Raspberry Pi, ESP32, and other microcontrollers. They are capable of returning calibrated spectral intensity values across several defined wavelength bands, enabling fine-grained spectral sensing in compact and mobile systems.
