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.
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.
