WiSens Underwater Loggers

The WiSens series comprises a family of autonomous sub-surface data loggers engineered to measure and record physical and chemical water parameters across fresh and marine environments. Operating via internal battery power, each cylindrical logger tracks metrics such as temperature, depth, conductivity, turbidity, and wave dynamics depending on the chosen model variant. The units function as standalone recording nodes deployed in aquatic ecosystems for short campaigns or multi-year campaigns.

Unlike conventional underwater loggers that require proprietary software interface cables and dedicated desktop systems, the WiSens family integrates an internal web server accessed locally via Wi-Fi. Users connect directly using any standard smartphone, tablet, or laptop browser simply by toggling a magnetic switch, allowing instant configuration, status checks, and data offloading in standard formats.

Key Features

  • Embedded Wi-Fi Access: Connects directly to any web-enabled device (iOS, Android, Windows, Mac) without requiring specialised interface software.
  • Magnetic Activation: Features a simple magnetic switch or activating clip to trigger internal Wi-Fi transmission safely while sealed.
  • High-Capacity Memory: Internal flash storage securely captures up to 2.5 million individual measurements across flexible sampling intervals.
  • Long-Term Deployment: Powered by user-replaceable high-capacity lithium cells capable of maintaining continuous operation for several years.
  • Robust Form Factor: Compact 40 mm diameter cylindrical housing constructed with marine-grade materials and optional anti-fouling copper shields.

Applications

  • Coastal oceanography, estuarine surveys, and long-term marine environmental monitoring
  • Limnological studies, freshwater lake profiling, and river network analysis
  • Wave height measurement, tide tracking, and hydrodynamics research
  • Fishery gear monitoring, net immersion tracking, and underwater structure deployment
