Product Description

The HOBOnet Wireless AeroCone® Rain Gauge records rainfall in 0.2-millimeter increments.


HOBOnet Wireless Sensors communicate data directly to the RX3000 weather station or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset’s innovative cloud-based software platform.


Sensor Features



  • Resolution of 0.2 millimeters

  • Bird spikes

  • Debris screen that locks in place

  • Designed to meet World Meteorological Organization (WMO) guidelines.


Wireless Features



  • 900 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

  • Simple button-push to join the HOBOnet wireless network

  • Onboard memory to ensure no data loss

  • Powered by rechargeable AA batteries and built-in solar panel.


Note: A complete HOBOnet system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters can be added to extend the range.
