AS73211 - True Color Sensor IC

True Color Sensor IC with I²C interface for relative and absolute color measurement

 

I²C interface for relative and 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.
