VEML6035 Ambient Light Sensor Module 16-bit High Sensitivity I2C Interface Brightness Detection Board For Arduino Raspberry Pi Light Intensity Measurement

VEML6035 Ambient Light Sensor Module

📌 Product Overview VEML6035 is a 16-bit low-power, high-sensitivity CMOS ambient light sensor module. It communicates via I2C interface with simple 12-bit commands. Built-in photodiode, amplifier and analog/digital circuits are integrated in a single chip. It features active interrupt function, which triggers an alert when light value exceeds the threshold window to reduce the load of main controller. It has excellent temperature compensation and stable output under temperature changes, no external RC low-pass filter is required for refresh rate setting. It supports programmable shutdown mode, the current can drop to 0.5 μA in shutdown state. Widely used for brightness auto-adjustment of screen, lighting control, industrial light intensity detection and DIY embedded projects. ✨ Core Features

• 16-bit high resolution, high sensitivity ambient light detection
• Built-in temperature compensation, stable output under temperature variation
