Spiio Soil Sensors

Illuminating the World Below Through Actionable, Site-Specific Data

Build your turf management strategy from the ground up. Spiio™ soil sensors provide precision insights into crucial components of turf health beneath the surface, including soil temperature, moisture, and salinity. These autonomous soil sensors gather site-specific data hourly and relay it to your dashboard, accessible on your smartphone or computer, at your chosen frequency. Simply subscribe, connect, and bury your sensors to start collecting actionable insights.

Key Sensor Measurements:

  • Temperature – Ranges from -4 to 158°F (-20 to 70°C)

  • Moisture – Capacitive sensor calibrated to measure volumetric water content (VWC) displayed as a %

  • Salinity – Displays electrical conductivity in dS/m, mS/cm, or TDS

  • Light – Collects light volume in Lux or footcandles when buried with the top exposed

Applications in Turf Management:

  • Soil temperatures triggering preventative patch disease treatments

  • Evaluation of soil flushing operations to reduce salinity

  • Low-temperature bermudagrass tarping

  • Cart traffic decisions following rain events

  • Pre-emergent weed applications

  • Freeze/thaw cycles under tarps in northern climates

  • Shade studies to improve growing environments

  • Irrigation requirements

  • Stakeholder reports and capital planning

Users can log in using the smartphone app or through a web browser on their desktop, laptop, or tablet to view key metrics on their properties anytime, anywhere. Users can also monitor specific data regions by establishing custom thresholds to help make better-informed decisions.


Data-Driven Insights to Meet Industry Demands

Technical Information

  • Sensor data is generated hourly and transmitted through wireless cellular communications to a cloud-based dashboard.

  • Four key measurements are continuously collected:

    • Temperature

    • Moisture

    • Salinity

    • Light

  • Compact design: Sensor dimensions are 7.1 in x 1.9 in x 1.9 in (180 mm x 47 mm x 48 mm).

  • Can be buried at varying depths (signal permitting).

  • Battery lifespan: 3 to 5 years.

The dashboard allows users to access relevant soil data and review historical values to support better decision-making. The platform also integrates hyperlocal GPS weather data, reducing reliance on less geographically relevant weather sources.


Focused Weather Forecast Data

The Digital Dashboard

"Spiio has turned out to be a game-changer on the course. With multiple microclimates throughout our property, it has given us the ability to track soil temperatures for specific application timing such as seed-head suppression. The ability to see significant data such as temperature, moisture, and salinity gives us immediate insight into what is happening below the surface. The light sensor has also given us the data needed to remove problem shade areas around our putting surfaces."

Tim Zevotek, Director of Agronomy, Roaring Fork Club, Basalt, CO

The weather tab on the dashboard offers forecast data within 3.25 square miles (8.5 km²). This includes:

  • Ambient temperature

  • Wind speed

  • Relative humidity

  • Precipitation

  • Evapotranspiration (ET)

  • Dew point

  • Sun hours

Weather Widgets:

  • Provide hourly breakdowns

  • Include color-coded thresholds that are customizable
