Product Overview
The VEML3235SL is an advanced, low-power, high-sensitivity ambient light sensor utilizing CMOS technology and an I2C interface. It offers simplified operation through I2C commands and integrates a photodiode, amplifiers, and analog circuits on a single chip. Designed to mimic human eye response with excellent spectral sensitivity, it features robust temperature compensation and a refresh rate setting that eliminates the need for external RC filters. The device supports a software shutdown mode for ultra-low power consumption (< 1 A) and operates within a supply voltage range of 2.6 V to 3.6 V, capable of detecting a wide spectrum of ambient light.
