Product Introduction

---

How much do you know about color? Do you want to know the true color? Your eyes may deceive you, but sensors won't. The AS7341 visible light sensor can tell you the truest color.

Gravity:AS7341 visible light sensor adopts the new generation AS7341 spectral sensor IC launched by the well-known ams company in the industry. The sensor has 8 visible light channels, 1 scintillation channel, 1 NIR channel and 1 channel without filter. The sensor has 6 independent 16-bit ADC channels and can process data in parallel. The sensor has two high-brightness LEDs on board to provide supplementary light in dark environments.
