Added Value of Using the AS7211

Applications

Sense ambient light, dim and maintain brightness of luminaires

and lamps in local loop control, automatic lumen maintenance,

flexible network connectivity and simple control of luminaires

and lamps.

• LED and fluorescent luminaires, troffers, high-bays

• Track-head and downlights

• LED and fluorescent replacement lamps

• Energy efficient installations, such as California Title 24

type energy code requirements

Benefits

Features

• Accurate control of daylight-responsive lighting

• Calibrated photopic sensing for direct lux

compensation for daylighting systems

• Automatic lumen maintenance over

temperature and time

• Autonomous lumen output adjustment

independent of LED aging effects

• Direct serial interface for connection to

standard networks

• Simple UART interface for connection to network

hardware clients for protocols such as Bluetooth,

ZigBee and WiFi

• Simple lamp or luminaire configuration and

commissioning using defined command set

• Smart Lighting Command Set (SLCS) uses simple

text-based commands to control and configure a

wide variety of functions

• Compatible with standard dimmer controls and

occupancy sensors

• Directly interfaces to 0-10V dimmer controls and

standard occupancy sensors

• Directly interfaces to LED driver or FETs

• Built-in PWM generator to dim LED lamps and

luminaires

• 12-bit resolution for precise dimming down to 1%

• Directly interfaces to ballast via 0-10V

• 0-10V analog output for control of conventional

fluorescent or other dimming ballasts

• Small package, wide operating range with

critical optics built-in

• 20-pin LGA package 4.5mm x 4.7mm x 2.5mm with

integrated aperture -40°C to 85°C
