ams – AS7225: Tunable-White Lighting Smart System Sensor


The AS7225 is equipped with the product family’s industry-first embedded tri-stimulus CIE XYZ color sensor to enable precise color sensing with direct mapping to the International Commission on Illumination (CIE) 1931 color space which is recognized as the standard coordinate definition for human color perception. CCT and daylighting tuning directives are communicated to the host microprocessor via an industry standard I2C interface, allowing IoT smart lighting manufacturers to avoid costly calibration and tuning algorithm development and reduce time to deployment.
