AS7211 IoT Smart Daylighting Manager

Network-enabled daylight sensing and integrated IoT luminaire management


AS7211 is a networking-enabled IoT Smart Lighting Manager with embedded digital ambient light sensor provides closed-loop and automatic daylighting management. 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 or analog 0-10V to standard dimming ballasts. A simple text-based Smart Lighting Command Set and serial UART interface, enables easy integration to standard network clients.
