AS7211 Smart Daylighting Manager with Fully Integrated Daylight Sensor, Control and Network Interfaces The AS7211 Smart Lighting Manager device is an intelligent, General Description photopic-sensor based light manager that enables automatic daylight level adaptation and energy conservation for next generation lighting systems. It is part of the ams Cognitive Lighting family of products that enable lights to be aware and adapt to their surroundings and autonomously meet human and energy conservation lighting needs. The AS7211 is equipped with an advanced Cognitive Light Engine (CLE) to optimize daylight harvesting and control either dimming ballasts or LED drivers. Ambient light sensing is achieved by way of integrated nano-optic deposited interference filters which deliver high-stability over time and temperature. The LGA package includes a built in aperture to control light entering the sensor array. A direct connection to a local sensor networks (LSN) enables integration with external occupancy sensors, dimmers or bridges. The AS7211 connects to standard 0-10V dimmers inputs and drives 0-10V dimming ballasts/drivers for fluorescent lighting or LED drivers for LED lighting. A UART interface is provided for remote configuration, control and management of the CLE. This UART inter face responds to simple Smart Lighting Commands.
