4. Using a flat bladed shovel, define three sides of a square 18” wide by 18” in length and 6” deep . This slit should be U shaped (see figure 3) . Work the shovel under the sod at a depth of about 4 inches and roll back the sod leaving exposed soil 3 to 4 inches deep . About 6 inches from one side of this opening, dig a similar opening and hole to accommodate a 7” valve box . This valve box (wiring box) will be used to splice additional wire from the sensor to the zone wire identified in Step 3 . Dig a slit trench from the 7” wiring box location to the base of the 18” square opening created for the sensor (see Figure 4) .5. Place the sensor horizontally in the loose soil at the bottom of the U-shaped cavity with the sensor wires running along the trench that leads to the wiring box . Pack loose soil firmly around the sensor rods to a depth of about ½ inch . Then pull the sod back over the sensor and pack it down firmly .18"18"Figure3SMRT-Y Soil Moisture SensorFigure47.
