ams — AS7225: Tunable White and Daylighting Smart Sensor

The AS7225 tunable white and daylighting smartsensor/director incorporates an embedded digital tri-stimulus chromatic ‘calibrated-for-life’ nano-optic sensor providing direct CIE1931 XYZ and CIE 1976 u’v’ coordinate mapping.

Adaptive algorithmic support enables a companion microprocessor to implement closed-loop, autonomous adjustment of variable CCT and daylight responsive LED lamps and luminaires. The AS7225 arrives pre-calibrated, and is designed for rapid integration into white-tunable and daylight responsive luminaire designs, delivering directives to the local microprocessor via an industry-standard I²C bus.
