Fermion: AS7341 11-Channel Visible Light Sensor

We live in a colourful world, but how much do you really know about colour? Your eyes may deceive you, whilst sensors don’t lie! This AS7341 11-Channel Visible Light Sensor-Breakout can tell you the truth about the colour around you and your project.

The DFRobot AS7341 11-Channel Visible Light Breakout Board employs the new generation of AS7341 spectral sensor IC launched by the well-known AMS company. The sensor features eight channels for visible light, one channel for near-IR, and one channel without a filter. It also integrates a dedicated channel to detect ambient light flicker.

This sensor comes with 6 independent 16-bit ADC channels for data processing in parallel. The two onboard extra-bright LEDs can supply light in a dark environment.
