6.5.4 Positioning Control Sensor
The control sensor is attached to the tree trunk at a height of 2-3 m. For methodological
reasons, it makes sense to use the same mounting height for all control sensors in all projects.
The same applies, of course, to the TMSO.CU if it is to take on the role of a control sensor.
6.5.5 Examples
If the local conditions do not allow the consideration / optimization of all parameters, priorities
must be set.
For example, if a tree is south facing when viewed from the TMSO.CU, a TMSO.IM would need
to be attached to that tree on the side facing away from the TMSO.CU to ensure the best solar
irradiation. On the other hand, this would be the worst conceivable position for the radio link,
as the tree blocks the line of sight (
).
If the tree is close enough to the TMSO.CU, a connection through the tree is also possible. In
this case, the sensor should actually be positioned for the best solar irradiation.
If, on the other hand, the tree is far away and radio communication is no longer guaranteed on
the side facing away, this must be compensated for by giving up some of the solar radiation
and the sensor must be attached to the side of the tree, for example (
).
