Onset's HOBO® ZW Series is a family of wireless data nodes for centralized monitoring of energy use and environmental conditions in buildings. HOBO ZW Series data nodes reduce the cost and complexity of data collection by measuring, recording and transmitting real-time energy use and environmental data from dozens of points to a central PC. Different from traditional data loggers, HOBO data nodes work together in a self-healing wireless network to transmit logged data to a PC at regular intervals. This eliminates the need of having to spend time retrieving collected data from individual data loggers deployed throughout a facility. The wireless nodes can measure temperature, relatively humidity, kilowatt hours, CO2, AC voltage, amps, gauge pressure, and a variety of other parameters. Easy to install in any facility, HOBO data nodes harness the power of self-healing MESH networking technology. This ensures that data is automatically routed back to a PC without manual intervention, while making it fast and easy to set up a sensor network.
