Provides a farm management system integrated with proprietary soil sensors for moisture, temperature, and EC.
METER Group
United States · Company
Scientific instrument company producing research-grade soil moisture sensors (TEROS series) and data loggers.
Manufacturer of high-precision multi-depth soil moisture and salinity probes used in research and commercial agriculture.
Creator of the Arable Mark, an in-field device that collects weather, plant health, and soil moisture data simultaneously.
Develops wireless, low-power LoRaWAN soil moisture probes designed for easy integration into existing IoT networks.
Finnish company offering fully buried wireless soil sensors that transmit data through soil/clay/concrete.
Specializes in Time Domain Reflectometer (TDR) soil moisture sensors that remain accurate in high-salinity soils.
Provides vertical soil moisture probes and 'Crophesy' software to analyze root activity and soil water balance.
Manufacturer of high-quality instruments for plant science and soil moisture measurement, including the ThetaProbe.
Produces wireless soil probes that measure NPK, pH, and moisture at multiple depths in real-time.
Soil moisture sensor networks deploy LoRaWAN or NB-IoT probes at multiple depths to capture volumetric water content, salinity, and temperature, transmitting data to cloud dashboards and edge-based irrigation controllers. Algorithms interpret soil tension curves and evapotranspiration forecasts, then open valves or pulse drip lines only where water deficits exist, enabling true variable-rate irrigation.
Large-scale orchards, vineyards, and outdoor cannabis farms rely on these networks to comply with water regulations, optimize energy use, and document stewardship for certification schemes. Vendors such as Sentek, AquaSpy, and Arable integrate moisture telemetry with pump automation, allowing growers to shave peak electrical loads and reduce runoff.
Emerging systems will fuse moisture data with satellite SAR imagery and predictive weather models to orchestrate irrigation cooperatives across entire watersheds. Remaining hurdles include sensor calibration across diverse soil textures, vandalism in rented fields, and the labor required to install dense probe networks. As ruggedized plug-and-play nodes emerge, moisture telemetry will become a default layer in precision irrigation stacks.
