Description:
The Waveshare AS7341 Spectral Color Sensor Module is a high-precision, multi-channel visible spectrum sensor designed for advanced light and color measurement applications. Based on the powerful AS7341 chip, this module features 8 individual visible spectrum channels, 1 near-infrared (NIR) channel, and 1 clear (unfiltered) channel, making it ideal for projects that require accurate spectral analysis.
Equipped with 6 independent 16-bit ADCs, the sensor enables simultaneous, parallel data processing for faster and more efficient readings. Its I2C interface ensures easy integration with a wide range of microcontrollers and platforms, including Arduino, Raspberry Pi, STM32, and other development boards.
Whether you're building a portable spectrometer, conducting color calibration, or exploring scientific sensing, the Waveshare AS7341 offers reliable performance and rich spectral data in a compact form factor.
