HOBO ZW Wireless Sensor Networks

A family of wireless data nodes that provide centralised monitoring of energy and environmental conditions in a building.


Key Features:

  • Centralised building performance data collection
  • Transmission of real-time data wihtin a self-healing mesh network eliminates line-of-sight issues
  • Automatically routes data back to the receiver
  • Onboard buffer memory
  • Alarm notification via email
  • HOBOnode Manager's Network Map provides at-a-glance view of your network
