The Ambient 3 Click Board™ is calibrated XYZ chromatic smart lighting director, providing the measurement data in digital format over the I2C interface. It utilizes the AMS AS7225, a miniature light sensor with UART and I2C interfaces. Packed in a small casing, this sensor can provide calibrated for life nano-optic sensor providing direct CIE1931 XYZ and CIE 1976 u’v’ coordinate mapping.
A well-proven, integrated tri-stimulus sensing element designed to meet the XYZ standard observer response that mimics the human eye and is extremely stable over both operating temperature and time. The device contains a 16-bit integrating analogue-to-digital converter, which integrates current from the photo-diodes. To ensure the integrity of the data, upon completion of an integration cycle, results are transferred to double-buffered registers.
