DFRobot Gravity AS7341: 11-Channel Visible Light Sensor - Spectral Sensing

Description:

We live in a colorful world, but how much do you really know about color? Your eyes may deceive you, while the sensors don’t lie. This Gravity: AS7341 11-Channel Visible Light Sensor can tell you the truth about color.

Gravity: AS7341 11-Channel Visible Light Sensor employs the new generation of AS7341 spectral sensor IC launched by the well-known AMS company. The sensor features eight channels for the visible light, one channel for near-IR, and one channel without a filter. Also, it integrates a dedicated channel to detect ambient light flicker. Besides that, this sensor comes with 6 independent 16-bit ADC channels for data processing in parallel. The two on-board extra-bright LEDs can supply light in a dark environment.
