Adura Technologies

The Leader in Wireless Lighting Control
www.aduratech.com

2006 | Western Region | $20.6 Million Funded

The Adura Lighting Control System is a powerful energy management platform comprised of six simple components: a web-based dashboard, an internet-connected Gateway, Light Controllers that are installed within light fixtures, occupancy sensors, daylight sensors and wall controls. Adura’s core wireless technology was developed at the University of California, Berkeley. Adura’s system uses standard IEEE 802.15.4 low-power radios that communicate several hundred feet using very little power. By forming a self-healing, adaptive mesh network, our wireless controls communicate over much longer distances and maintain reliable connectivity, even in difficult environments.
