MODEL 3051 : Soil Moisture Sensor

General Description:

The Model 3051 Soil Moisture Sensor measures the dielectric constant of soil, which is directly related to water content. The probe consists of a electronic module encapsulated in one end of the cylindrical housing and a moisture sensing element. The sensor measures an 18 in. section of soil starting 1/2 in. up from the bottom. The sensor can be placed in any direction or depth but must be in direct contact with the soil. A temperature sensor may be added to the package.
