(5) Home – Click the Home button to display the data for a month where today’s date is centered. The default view shows a
month where today’s date is on the right edge of the graph.
(6) Scroll to different date – Click and drag the scroll box at the bottom of the graph display a different date range on the
graph.
(7) Scale – Click the Scale button to control the level of detail by zooming in or out.
(8) Center – Click the Center button to center the graph lines horizontally.
(9) Test – Click Test to display a current reading from the sensor.
(10) Moisture percentage – When the graph is in Scale 1 or 2, this reading displays for the location of your cursor. In the
illustration, notice that the cursor is positioned near the top of the graph and the moisture percentage reading
corresponds to that location.
Possible Graphs
If you have a biSensor soil moisture sensor installed and you are using one of the watering strategies based on moisture sensor
readings, your soil moisture graphs might look like one of those illustrated below. Use the following information to interpret the
graph and to determine whether you need to make changes to your settings.
Good Graph
This example of a good graph shows the following desirable
characteristics:
• The leading edges for the moisture graph are sharp and
clean indicating that the moisture is reaching the sensor
while the zone is being watered.
• The upper and lower thresholds are separated
sufficiently to allow multiple days between watering.
• The watering days are spread out allowing the surface of
lawn to dry somewhat thereby helping to prevent
disease.
• The days between watering vary somewhat to account
for changes in the moisture requirements of the grass.
• The curves have good vertical movement indicating that ground is not saturated.
Good Graph with Initial Peaking (High Peaks after Watering)
This example of a good graph shows the following characteristics:
• An initial high peak that falls off rapidly and then
decreases normally.
• The moisture content is greater than the field capacity
of the soil. The moisture is moving below the sensor and
wetting the lower portions of the root zone.
