AS7225 Smart Lighting Sensor - Director

AS7225 Smart Lighting Sensor - Director

ams' AS7225 is a tri-stimulus, tunable white and daylighting smart sensor/director. This sensor incorporates an embedded digital tri-stimulus chromatic nano-optic sensor providing direct CIE1931 XYZ and CIE 1976 u'v' coordinate mapping.

The 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 is designed for rapid integration into white-tunable and daylight responsive luminaire designs and applications via standard I2C interface. This sensor has a temperature operational range of -40°C to +85°C and comes in a very small 20-pin LGA package (4.5 mm x 4.7 mm x 2.5 mm). In addition, there is a demo board available. The AS7225 is ideal for daylight responsive lighting, commercial/retail/residential lighting systems, and Internet of things(IoT) smart lighting applications.
