The Geolux SmartObserverPlus is a versatile, next-generation datalogger designed for reliable hydrological and meteorological monitoring, featuring expanded connectivity options, enhanced storage capabilities, and customizable operation through MicroPython.
The Role of Dataloggers
In hydrometeorological monitoring, dataloggers are the backbone of automatic stations. Their responsibilities include data retrieval, instrument configuration, calibration, power management, data recording, and real-time transfer. Operating in remote and harsh environments, they must be durable, require minimal maintenance, and ensure uninterrupted data collection over long periods.
Versatile Dataloggers
As climate change accelerates and extreme weather becomes more frequent, expanding the global monitoring network requires dependable dataloggers. Limited cellular coverage in remote areas highlights the need for satellite or radio options, while low power consumption is crucial to avoid reliance on large solar panels that may be prone to vandalism.
Geolux addressed these challenges with its first SmartObserver datalogger, launched over five years ago. It featured IoT integration with the HydroView portal, an MPPT battery charger, Modbus and SDI-12 support, and multiple communication options including cellular, LoRaWAN, and satellite. SmartObserver has since been deployed worldwide.
The Next Generation
The SmartObserverPlus builds directly on customer feedback to enhance reliability and versatility. Key improvements include:
- Expandable storage: microSD slot and USB host port for data storage, transfer, and firmware updates
- Simplified configuration: USB device interface replaces RS-232 for easy PC connection
- Expanded inputs: three Modbus, two SDI-12, and four high-precision 24-bit analog inputs (voltage or current)
- Flexible I/O: four digital input/output connectors for sensors or external devices like alarms
- Ethernet interface: supports both wired internet delivery and local instrument integration (e.g., cameras)
- Wireless flexibility: two miniPCIe slots for cellular, Iridium SBD, or LoRaWAN modules, configurable in single or dual setups
- Custom operation: MicroPython support allows advanced users to run scripts or full programs to process data or control instruments
Conclusion
With its robust design, flexible connectivity, expandable storage, and support for MicroPython, the Geolux SmartObserverPlus redefines what a modern datalogger can do. It ensures reliable data collection under extreme conditions while offering unmatched customization for advanced users. This next-generation platform strengthens the backbone of hydrological and meteorological monitoring networks worldwide.
