ams – AS7221: Smart Lighting Manager for Spectral Tuning IoT Lighting Control


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 0V to 10V dimmers, with control outputs that include direct PWM to LED drivers and analog 0V to 10V to dimming ballasts. A simple text-based Smart Lighting Command Set and serial UART interface enable easy integration to standard network clients.
