DFRobot Gravity AS7341 11-Channel Visible Light Sensor - I2C Interface
The DFRobot Gravity AS7341 is an 11-channel spectral sensor module compatible with 3.3V/5V systems like Arduino, Raspberry Pi, and ESP32. It provides high-resolution color analysis across eight visible light bands, plus near-IR and flicker detection channels for precise lighting and colorimetric applications.
Features
- 11-channel spectral sensing: 8 visible light bands, 1 near-IR channel, 1 clear channel.
- Integrated 50Hz/60Hz ambient light flicker detection for stable lighting control.
- Six independent 16-bit ADC channels for parallel, high-precision data acquisition.
- Onboard high-brightness LEDs for illumination in low-light conditions.
- Gravity-series connector for plug-and-play compatibility with DFRobot ecosystem and standard I2C interface.

The DFRobot Gravity AS7341 Visible Light Sensor employs the advanced AS7341 spectral sensor IC from ams OSRAM AG. It utilizes a configurable array of optical filters to dissect incoming light into eight specific wavelength bands across the visible spectrum (405–690nm), alongside dedicated channels for near-infrared and unfiltered light measurement. This enables precise spectral analysis far beyond simple RGB sensing.
The module integrates six independent 16-bit analog-to-digital converters, allowing simultaneous sampling for high-speed, accurate color data capture. An integrated flicker detection engine identifies 50Hz or 60Hz artificial lighting interference, critical for stable readings in indoor environments. Two onboard high-current LEDs provide supplemental illumination, ensuring reliable sensor operation in dark or controlled lighting setups.
