Location / Minimum height
The DuoFern Environmental Sensor must be installed at a minimum height of
2 metres.
Select an installation position on the building where wind, rain and sun can be
detected by the sensors without any impeding structures. No structural parts may be
installed above the DuoFern Environmental Sensor from which water can drip onto
the precipitation sensor after it has already stopped raining or snowing. The build-
ing or, for example, trees must not cast shadows onto the DuoFern Environmental
Sensor. A distance of at least 60 cm must be allowed under the DuoFern Environ-
mental Sensor to permit proper wind measurement and to prevent it being covered
by snow.
The DuoFern Environmental Sensor must be installed on a vertical wall (or
mast) and aligned horizontally in the transverse direction.

Fasten the bracket perpendicularly to the wall or mast.

cular rib facing upwards.
