HOBO MicroRX Station

The compact and rugged HOBO MicroRX Station is an easy-to-deploy, low-cost cellular solution for long-term, reliable field monitoring. Two power source options are available: a solar panel for extended deployments and user-replaceable batteries for flexible mounting in covered or protected locations. The station includes inputs for up to five of Onset’s research-grade plug-and-play sensors and can be ordered with an additional water level sensor input with integrated flow conversion. Configurable station-side alarms trigger immediate notifications of critical conditions, and Onset’s cloud-based HOBOlink platform makes it easy to view, access, and share data.
