Mikroelektronika MIKROE-3686 AS7225 Calibrated XYZ Chromatic Smart Lighting Director, UART, I2C, 3.3

Technical description of the product (MIKROE-3686):

The MIKROE-3686 AS7225 is a calibrated XYZ chromatic smart lighting director, providing measurement data in digital format over the I2C interface. It utilizes the AS7225, a miniature light sensor with UART and I2C interfaces. Packed in a small casing, this sensor provides a calibrated-for-life nano-optic sensor offering direct CIE1931 XYZ and CIE 1976 u’v’ coordinate mapping. A well-proven, integrated tristimulus sensing element is designed to meet the XYZ standard observer response, mimicking the human eye and being extremely stable over both operating temperature and time. The device contains a 16-bit integrating analog-to-digital converter, which integrates current from the photodiodes. To ensure data integrity, upon completion of an integration cycle, results are transferred to double-buffered registers. Type: Optical. Applications: It can be used for CCT chromatic tuning luminaire systems, backlight dimming applications for mobile and handheld devices, light metering applications (lux meters), and similar. On-board modules: AS7225, a calibrated XYZ chromatic smart lighting director with UART and I2C interfaces, from ams AG. Key Features: Standard observer tristimulus (XYZ) interference filters, spectral response similar to the human eye, low power consumption, compact design ideal for building IoT applications. Interface: I2C, UART. Click board size: M (42.9 x 25.4 mm). Input Voltage: 3.3V.
