Soil temperature, moisture and conductivity sensor
The SM-3 soil moisture sensor is a very precise sensor and integrates temperature, conductivity and soil moisture measurements in a single instrument.
The operating principle is based on the FDR (Frequency Domain Reflectometry 70MHz) system for a precise measurement of the soil dielectric constant and therefore to measure the soil moisture content volume. For the temperature part it uses a PT100 thermo-resistance sensor. Steel spikes are inserted into the surface of the ground or in the section for a quick measurement of the ground parameters. It can be permanently left in the ground or used just to make quick and accurate measurements.
This sensor is built according to the WMO standards (World Meteorological Organization).
