The AS7331 is a low-power, low-noise integrated UV sensor designed for measuring UVA, UVB, and UVC radiation. It converts optical signals into digital results, offering continuous or triggered measurements. With adjustable responsivity, conversion time, and internal clock frequency, it achieves a wide dynamic range and high accuracy. The sensor features automatic power-down for low current consumption and supports various operational modes including CMD, CONT, and synchronized modes (SYN[x]). It is suitable for a range of applications requiring UV radiation measurement and analysis.
