The AS7225 tunable-white lighting smart system sensor allows lighting manufacturers to access the company’s closed-loop CCT tuning and daylight compensation, while retaining the existing host microprocessor architecture in their smart lighting design. The result is higher precision, more flexible LED binning, and lower system costs for tunable white lighting systems. The AS7225 is equipped with the 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. CCT and daylighting tuning directives are communicated to the host microprocessor via an I2C interface, allowing IoT smart manufacturers to avoid costly calibration and tuning algorithm development and reduce time to deployment. Pricing for the AS7225 spectral tuning IoT smart lighting manager is set at $2.40 each/5,000. For more details and a datasheet, visit:
