Gardena smart system smart Sensor 19040 Operator's Manual page 9

To select the correct location:
Correct location:
The 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.)
for which a status is to be displayed.
If you use drip irrigation, place the sensor near a dripping point.
If you would like to place the sensor in a planter, choose a spot at least 5 cm
from the edge.
If you would like to place the sensor in the lawn, first strip the top layer of the
lawn before continuing.
Place the sensor so that there are no obstacles between the sensor and the
gateway.
Incorrect location:
To rule out erroneous results caused by waterlogging, the sensor should not be
positioned in dips in the ground.
In direct sunlight, it should be noted that the measured temperature can differ
from the actual temperature.
When used in a flower pot, the sensor must be at least 5 cm from the edge of
the flower pot.
CAUTION!
Damage to the sensor from the lawn mower.
v The cutting height of the lawnmower must be at least 30 mm.
