Product advantages
Smart sensors for soil moisture measurement
The Senseca soil moisture sensor reliably measures volumetric water content (VWC) and soil temperature, providing a solid data basis for informed decisions in agriculture, hydrology, and geology. Thanks to its capacitive measuring principle with two electrodes, the sensor enables fast, precise, and soil-friendly measurements directly in the field. Whether for controllable irrigation, analysis of water movements in the soil, or investigation of soil profiles, the soil moisture sensor helps you make your processes more efficient and data-driven.
- Reliable VWC database for optimized irrigation and targeted resource use
- Easy integration into your infrastructure thanks to MODBUS communication
- Robust and quick to install for field use
