AS7341-V1

AS7341‑V1: 10‑Channel Advanced Spectral Sensor for Precision Color & Light Sensing

The AS7341‑V1 is a compact, low‑power spectral detector featuring ten discrete photodiodes that cover the visible to near‑infrared range (400 nm–1000 nm). Leveraging a 12‑bit ADC and an I²C interface, it delivers high‑resolution analog‑to‑digital values for each channel, enabling accurate color, light, and material analysis. Designed for integration into microcontroller and FPGA systems, it offers built‑in dark‑current correction, programmable integration times, and a fast shutdown mode for battery‑operated applications.

Its compact footprint (3 × 3 mm) and low current draw (< 1 mA typical) make the AS7341 ideal for wearable sensors, smart lighting control, agricultural monitoring, and consumer electronics that require reliable spectral data without sacrificing form factor.
