Soil temperature and moisture sensor
The SM-2 soil moisture sensor is a very precise sensor which integrates temperature 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 volume of soil moisture content. For the temperature part it uses a PT100 thermo-resistance sensor. Steel spikes are placed into the surface of the ground or in a section for a quick measurement of the ground parameters. It can be left permanently in the ground or used to make quick and accurate measurements.
This sensor is built according to the WMO standards.
