TCS34303
Product Description
Product Overview
The TCS3430 is an advanced digital Ambient Light Sensing (ALS) and CIE 1931 Tristimulus Color Sensing (XYZ) device. It features filters for precise optical response, enabling accurate measurement of ambient light and color. This allows for the calculation of chromaticity, illuminance, and color temperature, supporting a wide range of applications. Key benefits include improved ALS responsiveness, 10% accuracy for illuminance and correlated color temperature, and a compact, low-profile design.
