A compact, rugged, easy-to-deploy, low-cost cellular solution for long-term, reliable field monitoring. With two power options available (a solar panel for extended deployments or user-replaceable batteries for flexible mounting in covered or protected locations), this monitoring station includes inputs for up to five of Onset's research-grade plug-and-play sensors. (Sensors must be purchased separately.)

Configurable station-side alarms trigger immediate notifications of critical conditions, and Onset's HOBOlink cloud platform makes it easy to view, access, and share data. This station can also be ordered with an additional water level sensor input with integrated flow conversion.
