ams' Sensor-Integrated Smart Lighting Manager Enables IoT-Connected Daylight Harvesting
Fully Integrated AS721x Autonomous Daylighting Manager Enables Manufacturers to bring the Internet of Awareness™ to Lighting
Photopic sensors built with nano-optic filters integrated into the AS721x series are designed to help lighting manufacturers address the growing challenges of energy-saving lighting mandates, including daylighting controls. These challenges are more cost-effectively met by bringing the controls, connectivity, such as Bluetooth, and high-granularity sensing into the luminaires themselves.
"The AS721X family of smart lighting silicon photonics sensor solutions create a natural Internet of Things (IoT) sensor hub within smart buildings, which results in an Internet of Awareness™ through the convergence of IoT-connected lighting and sensor fusion," said Sajol Ghoshal, who is responsible for Emerging Sensor Strategies at ams. "The AS721X family, with Broadcom's groundbreaking, easy-to-use connectivity from their WICED™ Smart Bluetooth and SmartBridge platform, delivers a secure, plug-and-play connection to the IoT for big data aggregation and the anticipated wave of machine learning."
The AS721x family is ams' first platform technology of integrated sensor solutions that provide systemlevel sensing and control capabilities, greatly reducing system costs and shortening time-to-market. The AS721x Autonomous Daylighting Manager senses the ambient daylight and enables the delivery of constant lux levels in the space by managing subtle adjustments as the amount of outside light varies.
Integrating a sensor-based manager into each luminaire optimizes the overall responsiveness and efficiency of the lighting system, maximizing energy savings. The approach also delivers accurate lumen maintenance over time and temperature variations, and allows fully connected luminaire systems to respond to building- or space-level command and control strategies.
"ams' ground-breaking sensor-integrated manager series addresses head-on the lighting industry's desire for technically feasible integrated controls that are also cost- and space-effective," said Sid Shaw, Broadcom Senior Product Line Manager, Wireless Connectivity. "Combined with ubiquitous and standards based BT Smart connectivity, it's a solution that will truly revolutionize the lighting industry, delivering the kind of network-connected system approach that exemplifies the power of the Internet of Things."
Competitive offerings in the space are essentially "build your own" devices requiring discrete components, including sensors, processors, memory, and I/O chips, that require design, integration and timeconsuming programming of control and communications algorithms. In contrast, the AS721x family delivers a fully integrated solution, providing users with a high level of integration at far lower cost and complexity than using discrete components.
Additional attributes of the ams' AS721x Autonomous Daylighting Manager:
