Product Description
The DFRobot Gravity: AS7341 11-Channel Visible Light Sensor is a color sensor module for spectral analysis of visible light. It is based on the AS7341 sensor IC and provides 11 measurement channels, including 8 channels for visible wavelengths, one near-IR channel, one clear channel, and one dedicated channel for ambient light flicker detection.
For signal processing, the module integrates 6 parallel 16-bit ADC channels. Communication is handled through I2C, making the module suitable for microcontrollers, embedded systems, and measurement applications with low wiring complexity. Two integrated high-brightness LEDs provide illumination for the target in low-light environments, improving measurement consistency under dark conditions.
The module is intended for applications that require more detailed spectral evaluation than a basic RGB color sensor. Typical use cases include color identification, material differentiation, light source analysis, and detection of flicker components in artificial lighting.
Technical Features
- Sensor IC: AS7341
- 11 total channels: 8 visible spectral channels, 1 near-IR channel, 1 clear channel, 1 flicker detection channel
- 6 independent 16-bit ADC channels for parallel data processing
- Interface: I2C
