HOBOnet Manager



The HOBOnet Wireless Manager module is installed in an RX Station. Data is transmitted wirelessly from sensors across the network to the RX Station and then uploaded to HOBOlink, Onset’s innovative cloud-based software platform.

Highlighted Features

  • 922 MHz wireless mesh self-healing technology
  • 450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
  • Up to 50 wireless sensors per RX3000
  • Plugs into RX3000 Flex Port

In what environment does this communication operate?
