The AS73211 is a digital XYZ sensor with I2C interface for relative and absolute color measurement and control. The combination of True Color XYZ sensitized photodiodes with a filter function based on the standard CIE 1931/DIN 5033 (human eye perception) and used interference filter technology as leading and most accurate technology of three-range sensors makes the AS73211 more accurate than RGB sensors and guarantee this function without spectral changings over lifetime. The AS73211 is designed with a high dynamic range to measure any light in the visible range (VIS) in environments from sunlight to dark rooms, dimmed LEDs, or dark colored monitors.
