Description
Description
SMEC‑5™ is a basic volumetric water content sensor that provides a relative value of water volume in the soil. It is manufactured in Pullman, Washington by METER Group (formerly Decagon).
The SMEC‑5 sensor is buried in the soil at the desired depth, usually within or just below the root depth of the crop. Two sensors may be used at varied depths to measure “saturated” conditions for irrigation purposes.
SMEC‑5 is suitable for use by commercial agricultural growers, landscape managers, turf farmers, and soil scientists. When combined with Dyacon control modules and weather instruments, SMEC‑5 provides a robust solution with remote data telemetry to the DyaconLive web interface.
The capacitance/frequency technology provides a faster response to changing soil conditions than gypsum block technology.
Feature Summary
- Capacitance/frequency technology
- 70 MHz frequency minimizes salinity and soil effects
- Suitable for all soil and media types
- Fast response
- o% to 100% VWC
- Made in the USA
Key Features
Construction
SMEC‑5™ is fully potted and sealed for direct burial.
The 5 m cable is resistant to soil and sun exposure.
Sensor Output
Analog output, 10% to 40% of excitation voltage.
Installation
SMEC‑5™ soil moisture sensor is easily installed by the user’s digging a hole and sticking the forks into the side of the hole. Sensor should be installed with the prongs horizontal, one above the other (in other words, on edge).
Mounting
The soil moisture sensor is buried in the ground at the desired depth. The appropriate depth is application specific and may depend on the soil type, root depth, or as appropriate for applications such as leak detection.
