Gravity: AS7341 11-Channel Visible Light Sensor

Notify me when this product is available:

We live in a colourful world, but how much do you really know about colour? 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 colour.

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 onboard extra-bright LEDs can supply light in a dark environment.
