1. Where to use Your GARDENA Soil Moisture Sensor
The GARDENA Soil Moisture Sensor is designed to be used solely
outdoors in domestic and private gardens and in greenhouses to
control sprinklers and watering systems via a GARDENA Water
Computer and multi-channel control systems taking account the
soil moisture level.
It is not permitted to use the Soil Moisture Sensor for
industrial or commercial applications and in conjunction
with chemicals, foodstuffs, highly combustible or explosive
substances.
2. Safety instructions
Batteries:
For reasons of operational reliability the Soil
Moisture Sensor should only be operated with
two 1.5V (alkaline) round cells type IEC LR14.
To prevent failure of the Soil Moisture Sensor
due to weak batteries in conjunction with a
lengthy absence, batteries should be replaced
in due course.
This will depend on the previous operating
life of the batteries and the probable length
of absence, which should not exceed a year
in total.

Information regarding use:
The Soil Moisture Sensor is equipped with a
safety switch. If the sensor cable is damaged or
the batteries flat, the selected watering time of
the Water Computer will be used for watering.
The spread of moisture in the soil after
watering or rainfall is rather slow.
In the worst-case scenario it may happen that
irrigation and a rain shower overlap until the
required soil moisture is attained.
3. Function
With the GARDENA Soil Moisture Sensor the soil moisture level
is taken into consideration for watering.
The Soil Moisture Sensor measures the soil moisture at the root
level of the plants automatically approximately every 10 minutes
and sends the measured results to the Water Computer.
1Indicator Activates display of moisture level last
button: measured.
2“Dry” LED Indicates that the Soil Moisture Sensor is
measuring dry in relation to the switching
controller 4.
3“Damp” LED: Indicates that the Soil Moisture Sensor is
measuring damp in relation to the switching
controller 4.
4Switching Sets the soil moisture level at which
controller: watering is to take place.
5If the battery LED flashes the batteries
Battery LED: have to be replaced.
If the batteries are flat and are not replaced, the connected
Water Computer will function with the watering program
selected.
vReplace batteries (see 7. Maintenance
“Replace batteries” ).
4. Initial Operation
vTo insert batteries (see 7. Maintenance “Replace batteries” ).
Correct location:
The Soil Moisture Sensor must be positioned at a location
in the watering area which is exposed to the same climatic
conditions as the plants (sun, wind, rain, etc.).
Incorrect location:
The Soil Moisture Sensor should not be covered by
neighbouring plants. Areas of shade should be avoided.
To rule out erroneous reaction results caused by waterlogging,
the Soil Moisture Sensor should not be positioned in dips in the
ground.

Connect adapter cable:
WARNING !
AThe tip of the sensor will only measure the soil
moisture correctly if the sensor tip is in full contact
with the ground on all sides! No air should be
trapped at the sensor tip in the ground.
1. Dig a funnel-shaped hole in the ground 1at least 12 cm
deep.
2. Break up the soil 1removed and take out any stones.
3. If the soil is dry, moisten.
4. Replace the damp broken-up soil 1in the funnel-shaped hole
without packing tight.
5. Immerse entire sensor tip 2in water (felt must be wet).
6. Insert sensor cable (long) 5in the sensor socket 6of the Soil
Moisture Sensor (on purchase this is already inserted).
7. Insert the Soil Moisture Sensor to the upper edge of the
sensor 3in the broken-up soil 1.
Here the sensor tip 2 must be in full contact with the damp
soil on all sides.
8. Press down the soil 1around the sensor 3lightly.
The Soil Moisture Sensor should not stand loose in the ground.
9. Water the area around the Soil Moisture Sensor with approx.
1 litre water.
Depending on the ground it may take several hours until the
Soil Moisture Sensor measures the actual soil moisture.
To ensure that the quantity of water delivered is registered by
the sensor tip when using the GARDENA Micro-Drip-System,
a drip head must be installed directly above the sensor.
vFit a Supply Pipe 4.6 mm (3 /16”) with drip head to the drip
head holder 4of the Soil Moisture Sensor.
1. Lay the sensor cable 5in / on the ground so that it cannot be
damaged or trip people up. The cable should be laid in the
ground in a bed of sand to prevent any damage being caused
by stones.
2. Fit adapter cable (short) 7to sensor cable 5(on purchase
this is already fitted).
3. Insert adapter cable 7in sensor connection of GARDENA
Water Computer.
If the sensor cable is not long enough, it can be extended with
the GARDENA Extension Cable Art. 1186 (up to 105 m).

5. Operation
The water requirement of plants depends on many factors, e.g.
type of plant, soil, sunshine, wind. To find the suitable switching
point of the Soil Moisture Sensor, it has to be observed during
irrigation over a period of approx. 1
- 2 weeks and re-adjusted
if necessary. If the soil moisture has exceeded the switching
point selected, the watering program of the Water Computer
is terminated prematurely or an outstanding irrigation process
blocked.
On delivery, the switching controller is set to the centre position,
which is suitable for normal non-forest soils (loamy humus).
For sandy soils the switching controller 8should be preset
slightly to the right (damper).
For potting soil the switching controller 8should be preset
slightly to the left (drier).
Increase soil moisture level:
vIf the soil seems too dry for an application (type of soil or plant
species), turn the switching controller 8to the right towards
“Damp” (e.g. with a coin).
Reduce soil moisture level:
vIf the soil seems too damp for an application (type of soil or
plant species), turn the switching controller 8to the left
towards “Dry” (e.g. with a coin).
The soil moisture can be displayed at any time with the Soil
Moisture Sensor. When the Soil Moisture Sensor shows
“Damp” A, watering is not carried out.
vPress indicator button 9.
The soil moisture value last measured is indicated for 1 minute
with the relevant LED ( “Dry” 0 or “Damp” A ).
During the minute in which the measured result is displayed, the
switching controller can be used to find the relevant switching
point by turning the switching controller until the display changes
from “Dry” 0to “Damp” Aor vice versa. If the display does
not change, the ground is either very dry or very damp.
To keep the soil moisture level as constant as possible, irrigation
should be carried out with short watering cycles and short wate-
ring times. This especially applies to flower boxes on balconies,
which have a watering time of <5 min.
