Operation Operation
Setting the Moisture Level
1. After connecting your
Moisture Sensor, hold
down the LEFT BUTTON[a]
and RIGHT BUTTON [b]
for at least five seconds
®The LED indicators[c]
will show the current
moisture level
2. There are five levels of
moisture indication
from through to as
shown on the sensor panel:
20% - 40% - 60% -
80% - 100% (volume
water content)
To set the threshold moisture
level (where the sensor
communicates to your
WX Tap Timer to stop
watering) press the
LEFT BUTTON to adjust
the indicator, and the
RIGHT BUTTON to
confirm your setting
3. The WX Tap Timer screen
[d] in Holman Home
will turn red when the

when moisture returns
below the threshold level
Positioning the Smart Moisture Sensor
1. Once paired, remove the black plastic
protectors from the end of each prong
2. Ensure the Moisture Sensor is placed no more than 30
metres line of sight from the WX1 or WX2 Tap Timer
ÁDo not use a hammer to install the Moisture Sensor
3. If the soil is very compressed, it is recommended to
soften up the soil by adding water before inserting
®This is especially important in clay soils
4. When placing the Moisture Sensor in the ground please ensure the
soil is wet before inserting the Moisture Sensor to prevent air gaps
®Air gaps will lead to wrong soil moisture measurements
5. Ensure the soil is properly compressed
®The density of the surrounding soil will
influence the measurement signal
6. Ensure the Moisture Sensor is installed in undisturbed soil
7. Ensure the Moisture Sensor is placed in a location where
there is minimal disturbance to roots and plants
8. Ensure the Moisture Sensor location is in an average location
of the climate conditions of the area you are watering
®For example, if your garden is mostly shaded,
place the Moisture Sensor in the shade
