Overview

The VEML6040A3OG is a high-accuracy RGBW color sensor that converts light intensity to digital 16-bit values via an I2C interface. It utilizes Vishay proprietary Filtron technology to achieve spectral sensitivity closely matching human eye responses across red, green, blue, and white channels.

Why Choose This Part

The sensor features excellent temperature compensation and a peak sensitivity of 0.005 lx per count, enabling operation under dark lens designs. Its Filtron technology provides best-in-class optical noise rejection and high linear dynamic range without needing external filters.

Applications

Backlight Adjustment
Automatically adjusts display brightness and color temperature based on ambient lighting conditions to improve user comfort.
Industrial Color Sensing
Used in production lines for sorting, identifying, or verifying the color consistency of products and packaging.
CCT Control
Calculates Correlated Color Temperature for smart lighting systems to maintain consistent white light quality.

Getting Started

Interface the sensor via the I2C bus (address 0x10) and configure the integration time using the configuration register to balance sensitivity and speed. For rapid prototyping, use the VEML6040-SB sensor starter board or an Adafruit VEML6040 breakout board with standard Arduino libraries.
