HOBOnet Sensors

Monitor conditions from anywhere with HOBOnet Temperature Sensor

A cost-effective and scalable solution for web-enabled monitoring of air, soil, and water temperatures. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX 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 software platform.

Important Information

A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor, OR one HOBO MicroRX Station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.

Onset HOBOnet Field Monitoring System

Transform the way you collect and view field data! With up to 50 wireless sensors streaming data back to one central, cloud-based weather station, you can now measure conditions over large areas once considered too costly or impractical to monitor.

The NEW HOBOnet Field Monitoring System from Onset provides a cost-effective and scalable solution for web-enabled monitoring of field conditions for applications such as crop management, research, and greenhouse operations.

How to Create a Dashboard in HOBOlink

This video shows users of the Onset HOBOlink cloud service how to create a dashboard for instant visualization of current and historical data. HOBOlink dashboards are a powerful and intuitive way to combine data from multiple Onset HOBO RX3000 or HOBOnet systems and show the data in a single view.

How To Add the Onset HOBOnet Manager to the RX3000 Station

This video explains how to install the Onset HOBOnet Manager in your HOBO RX3000 station. The Manager enables your wireless sensors to join a network and begin taking measurements and transmitting data.

How to Add Sensors to the HOBOnet Wireless Sensor Network

This video will show you how to pair a Onset HOBOnet wireless sensor to its HOBOnet RX3000 weather station.

How to Create a Map View of your HOBOnet Wireless System

This video will show you how to set up the Google Map feature for your HOBOnet Field Monitoring System.
