How much do you know about color? Do you want to know the true color? The eyes may deceive you, but the sensor won’t. The AS7341 visible light sensor can tell you the truest color.
Gravity: The AS7341 visible light sensor uses the new generation AS7341 spectral sensing IC launched by the well-known in the industry. The sensor has 8 visible light channels, 1 flicker channel, 1 NIR channel and 1 unfiltered channel. The sensor has 6 independent 16-bit ADC channels, which can process data in parallel. The sensor board has two high-brightness LEDs, which can be filled in low-light environments.
