probe

The Finapp probe is a patented CRNS soil moisture sensor that measures soil water content and Snow Water Equivalent across representative areas, continuously and without disturbing the soil. Unlike a buried point sensor, this soil moisture probe reads an entire field from a single pole-mounted unit: 5 to 10 hectares of coverage, down to 50 cm in the soil, with continuous data and no gaps.

Unique Pros

Two variables that normally require two separate instruments, delivered by one CRNS probe. Soil moisture on every model as standard, Snow Water Equivalent with a two-probe setup.

  • At scale. 5 to 10 hectares, 40 metres of snowpack
  • In depth. 50 cm underground, up to 10,000 mm water equivalent
  • Real time. No gaps
  • Non-invasive. Nothing buried, nothing disturbed

Patented Innovation

A patented CRNS soil moisture probe built around a Lithium-6 detector, with real-time validation on site. Finapp has patented the next generation of CRNS probes, built around a Lithium-6 detector.

  • Compact and light. 40×30×18 cm, ≈8 kg. Ready for the field, not just the lab
  • Muon counting on board. Real-time validation, right at the site
  • 0.5 Wh. True off-grid operation, wherever the data matters

Unlike conventional sensors, which need a dedicated instrument per variable and scale, Finapp covers it all with one design.

  • Two in one. Soil moisture standard, SWE with a two-probe setup
  • Same physics, scalable sensitivity. All models detect neutrons and muons; only the counting rate changes.
  • Every fields. Agriculture to civil protection to research

Connected by Design

Everything you need to get soil moisture data out is already inside the probe.

  • Datalogger built in. No extra hardware
  • Connected everywhere. Cellular, satellite, or radio, straight to the Finapp cloud
  • Your data, your way. API access or direct FTP transfer
  • A complete station. SDI-12 support plus optional rain, temperature, humidity, and pressure sensors

Probe operation

Measure water in soil and snow

The same probe works all year round: in summer it measures the water in the soil, in winter the water stored in the snowpack.
