Aanderaa SmartGuard Datalogger

SmartGuard is the next generation sensor and instrument HUB for Ocean, Lake, Reservoir, Estuary and River Hydrometric stations. It's a complete observatory node for advanced Hydrologic/Meteorological stations as well as for small stand alone stations.

  • Features
  • Specifications

Monitoring water and weather conditions is essential in many operations and the SmartGuard node is well suited for stand-alone stations powered by battery and solar power utilizing wireless real-time data communication. Designed for ease of integration of new and existing sensor technologies into a single Aanderaa observatory node with modern self-describing XML data output formats. SmartGuard interfaces with all Aanderaa atmospheric and in water sensors, along with most 3rd party sensors.
