EC-5 Soil Moisture Sensor

Low-Cost Single Sensor for Large Sensor Networks

The EC-5 offers research-grade accuracy at a price that makes large sensor networks economically practical. You can adequately characterize your site with sensors at multiple depths and locations, even if you're on a tight budget.

Designed for Accuracy

The EC-5 determines volumetric water content (VWC) by measuring the dielectric constant of media using capacitance/frequency domain technology. Its 70 MHz frequency minimizes salinity and texture effects, making this sensor accurate in almost any type of soil or soilless media. Factory calibrations for mineral soils, potting soils, rock wool, and perlite are included.

Easy Installation

At just 5 cm long with a measurement volume of ~0.2 L, this handy little sensor is easy to install in the field and can also be used in nursery pots. The EC-5's compact design makes it easy to push directly into undisturbed soil to ensure good accuracy.

Easy integration

The EC-5's analog signal means seamless integration with systems manufactured by other companies.

Reasons to choose the EC-5

Volumetric water content is the only measurement you need

Affordable

Simple sensor with excellent accuracy

Small volume of influence (e.g., field spatial variability, laboratory column studies, or greenhouse research)
