Solar panel, battery, temperature and relative humidity, global radiation, rain gauge and barometric
pressure are part of the main system. There are usually no long cables for these sensors. Wind speed and
Wind direction sensors will need a cable because they have to be mounted on the end of the pole. They
normally come with 3 m cable. The soil temperature sensor comes with 5 m cable. It has to go to the
ground at the desired depth. Leaf wetness comes with 5 m cable. This sensor is mounted in the canopies
of trees and vines.
Convection cup and global radiation sensor are mounted on top of the holder. They are dismounted
during transportation and have to be mounted after unpacking. Just push them under the 3 screws
which are prepared in the housing for each of them and fix the screws with a small screwdriver.
The solar panel might be clapped down for transportation. Screw the 3 screws in and it will be clapped
out. On some systems for cooler climate the solar panel can come on a separate holder. In this case
please fix this holder on the mounting pole by using the clamps which have been added to the package
for this purpose.
The temperature and relative humidity sensor should be mounted 2 m above the ground. This is the standard
measurement for this climate factors in agricultural meteorology.
The iMETOS is mounted on the post with two clamps. Make sure that the pole is buried as straight as possible.
How horizontal the climate station is mounted can be checked by the little water lens at the rain gauge.
On northern hemisphere the solar panel should be exposed to south and the same the global radiation
sensor. The wind direction sensor should point towards north and the wind speed sensor should point towards
The leaf wetness sensor comes with a cable tie to be mounted on a branch of the tree or vine or on the main
holder (next to the rain gauge) slightly inclinated. Please mount this sensor in a position with allows the sensor to
pick up the early rain and to stay wet in shadow.
The soil temperature sensor should be buried in the ground. How deep it should be buried is depending from
the goal which should be reached with the sensor. To have an impression of root growth and nitrogen mineralization
in vines or apples in early spring it is best be mounted at 10 to 20 cm. It you want to assess the emergence
possibilities of seeds it is depending on the sowing depth of the seed. Using it in corn (maize) would mean to mount it
at 5 cm and using it for sugar beets would mean to mount it at 2 or 3 cm only.
The wet and dry bulb temperature sensor is mounted in the height of the lowest plant organ which should
be protected from frost. Two clamps are packed with the unit to mount this sensor on the post.
Water level sensors are equipped with 15 m cable to give the sensor into the water. It is combined with a
barometric pressure sensor to give the actual air pressure.
