Soil Moisture (%)

This particular soil sensor measures volumetric water content. This means that the sensor measures the total amount of water in the soil in 0-100%.  

Soil Temperature (C°)

Along with the water content, the sensor also measures soil temperature. The temerpature sensor ranges from -40 to 80 degrees celcius. 

Electrical Conductivity (EC)

The third unit of measure on the sensor is electrical conductivity, measured in decisiemens per meter (dS/m). EC is commonly used in various fields, including agriculture and hydrology, to assess the salinity or ion concentration of water or soil.
