The Soil Moisture Sensor measures the soil moisture at the root
level of the plants. With the GARDENA Soil Moisture Sensor the
soil moisture level is taken into consideration for watering. The
Soil Moisture Sensor measures the soil moisture automatically
approximately every 10 minutes and sends the measured results
to the Water Timer.

remove the control panel from the casing.
Soil Moisture Sensor :
The Soil Moisture Sensor is equipped with a
safety switch. If the sensor cable is damaged
or the batteries flat, the Soil Moisture Sensor
is not recognised by the Water Timer any more.
If watering is controlled by the Soil Moisture
Sensor ( , , ) an emergency mode is
activated : watering every 24 hours with the
set watering duration, max. 30 minutes.
If watering is time-controlled the programme
is run without the sensor.
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.
