Remark

General description

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.

This product suits for the following applications:

  • Display calibration
  • Light metering
  • Fluid or reagent analysis
  • Color detection
  • LED feedback control
