The WiSens range comprises a family of compact, robust sub-surface data loggers engineered to measure and record critical physical, chemical, and hydrodynamic parameters across marine, estuarine, and freshwater environments. Operating on high-capacity replaceable lithium batteries, these self-contained cylindrical nodes provide multi-year deployment autonomy for continuous short-term campaigns or long-term monitoring network installations. Each model integrates an embedded local web server accessible via standard Wi-Fi, allowing technicians to configure parameters, check memory status, and download standard CSV/ZIP data files directly from any smartphone, tablet, or laptop without proprietary software.
The WiSens family introduces frictionless field operability via magnetic activation switches and native cross-platform web browser access. This capability is further supported by a dedicated ecosystem of protective cages, high-visibility orange housings, and specialised mooring or axial clamps designed to safeguard instruments in heavy-current or commercial fishing applications.
