Overview

The VEML6030 is a high-accuracy, 16-bit resolution ambient light sensor that communicates over an I2C interface. It is designed to mimic the human eye's spectral response and features a wide dynamic range from 0 lx to 140 klx, making it suitable for both dark environments and direct sunlight.

Why Choose This Part

The sensor features excellent temperature compensation and 100 Hz / 120 Hz flicker noise rejection to ensure stable readings in various lighting conditions. Its ultra-low power consumption of 0.5 uA in shutdown mode and 8 uA in active mode makes it ideal for battery-operated IoT devices.

Applications

Backlight Dimming
Adjusting screen brightness in mobile devices, tablets, and automotive displays to enhance user comfort and extend battery life.
Smart Lighting
Controlling indoor or outdoor lighting systems based on available natural light levels for energy efficiency.
Industrial Sensing
Monitoring light levels in industrial control systems or as part of a daylight-harvesting strategy in building automation.
