Sensor Installation
4.1 Soil Sensor Installation
The sensor can be oriented in any direction. However, orienting the flat side perpendicular to
the surface of the soil will minimize effects on downward water movement. There are two basic
methods to accomplish a high-quality installation.
4.1.1 Horizontal Installation
1. Excavate a hole or trench a few centimeters deeper than the depth at which the sensor is to
be installed.
2. At the installation depth, shave off some soil from the vertical soil surface exposing
undisturbed soil.
3. Insert the sensor into the undisturbed soil surface until the entire sensor is inserted. The tip of
each prong has been sharpened to make it easier to push the sensor into the soil. Be careful with
the sharp tips!
Note:
If there is difficulty inserting the sensor, loosen or wet the soil.
