The TCS3430 Daughter Board features advanced digital Ambient Light Sensing (ALS) and CIE 1931 tristimulus color sensing (XYZ). Each of the channels feature a filter to control its optical response allowing the device to accurately measure ambient light and sense color. These measurements are used to calculate chromaticity, illuminance, and color temperature that are used to support various potential applications. The TCS3430 is ideally suited for use in smartphone applications to improve color measurement and intensity of ambient light conditions. The sensor can also be used to assist the smartphone camera sensor with color sensing of ambient light to enhance and improve picture white balance to deliver more realistic and vibrant images. Typical applications include display brightness and color control for power management and best viewing experience and improved white balance and image correction for cameras.
