Adafruit AS7341 Spectral Light & Color Sensor Breakout – 10-Channel I2C Module
The Adafruit AS7341 10-Channel Light / Color Sensor Breakout is a powerful multi-channel spectrometer sensor designed for precise color detection, spectral analysis, and light measurement. Unlike standard light sensors, this module can detect specific wavelengths across the visible spectrum, along with near-infrared (NIR) and flicker detection, offering highly accurate color analysis beyond human vision.
Featuring 10 individual light channels, including 8 visible spectrum bands (415nm to 680nm), clear light, and NIR, the AS7341 provides detailed spectral data using a 16-bit ADC and advanced SMUX (super multiplexer) technology.
Designed with STEMMA QT / Qwiic connectors, it enables plug-and-play I2C connectivity with popular platforms like Arduino, Raspberry Pi, and CircuitPython boards, without the need for soldering.
With additional features like flicker detection, GPIO interrupt support, and low power consumption, this sensor is ideal for scientific, industrial, and creative applications requiring precise color measurement.
