Visible light sensor AS72 Series

LEDPWMIoT

The AS721x/AS722x are complete system-on-chip (SoC) sensor-integrated IoT smart lighting managers for color-tunable white lighting applications. They also support daylight harvesting and color/lumen maintenance lighting applications. 0-10V control and network-enabled high-level command inputs are combined with industry-standard PWM and 0-10V outputs for direct control of LED power systems. The Smart Lighting Director adds closed-loop sensing, providing tuning directives to an existing smart light architecture. Sensor-hub expansion capabilities include native support for various ams environmental sensors for added IoT flexibility. Non-networked versions support stand-alone color/lumen maintenance and daylighting functions for new designs and retrofits. Network-enabled daylight sensing and integrated IoT luminaire management Features Network enabled, high accuracy LUX control Compatible with standard dimmer, occupancy controls and ballasts Built-in PWM generator for precise 1% dimming 20-pin LGA 4.5mm x 4.7mm x 2.5mm, 0°C to +85°C Benefits Networked daylighting controls Direct 0-10V inputs/outputs Direct PWM interfaces Compact package with no added optics required General Description AS7211 is a networking-enabled IoT smart lighting manager with embedded digital ambient light sensor providing 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.
