The DataHub is a versatile data logging and telemetry instrument designed and manufactured by Van Walt in the UK. Designed principally for remote/off-grid applications DataHub is self-powered via internal batteries and a solar array or alternatively can be configured for mains power.
Suitable for use at a single monitoring location or as the central data management unit for more complex multi-parameter, multi-location sensor networks DataHub is perfectly suited for remote monitoring in environmental research, agri-research, brownfield development, mining/quarrying and many other applications.
DataHub is compatible with a wide range of support sensors enabling continuous and autonomous measurement of water level, flow, water quality, meteorological parameters and soil moisture. Capable of receiving simultaneous inputs from SDI-12, Modbus, analog and pulse, DataHub is an incredibly flexible and powerful data management unit.
All data collected is uploaded to the secure vanwaltCONNECT data portal accessible from PC and mobile devices.
