AS7221 CCT TUNING SMART LIGHTING MANAGER

Network-Enabled Sensing and Integrated IoT Luminaire Management for Spectrally Tunable Systems

AS7221 is a networking-enabled IoT Smart Lighting Manager with embedded tri-stimulus color sensing for direct CIE color point mapping and control. IoT luminaire control is through a network connection, or by direct connection to 0-10V dimmers, with control outputs that include direct PWM to LED drivers and analog 0-10V to dimming ballasts. A simple text-based Smart Lighting Command Set and serial UART interface, enables easy integration to standard network clients.
