2. 

Insert the thinner pole into the grounded one and fix it with the locking 

ring at the desired height with the use of a 13 mm wrench. 

3. Install the iMETOS station at 1.5 meter above the ground or depending 

on the crop height. Fix the iMETOS with the two clamps on the verti

-

cal pole using two 13mm-wrenches. Check the bubble level on the rain 
gauge to ensure the iMETOS is installed verticality of the pole and align 
the solar panel to face south (north in southern hemisphere).

SENSORS INSTALLATION:

•  Temperature and relative humidity sensor 

should be mounted be-

tween 1.25 m and 2 m above the ground, depending on the crop. 

Leaf 

wetness sensor

 can be tied to a branch of the plant or to the station 

holder (next to the rain gauge), slightly inclined, with the filter paper 

looking up. Mount it in a position that allows the sensor to pick up 
early rain and to stay wet in the shade.

•  Soil temperature sensor

 should be buried in the ground. The depth 

will depend on the application. To monitor root growth and nitrogen 
mineralization in vines or apples in early spring, it is best to install it 
at 10 to 20 cm depth. If you want to assess the emergence of seeds, 
install it at the sowing depth.

•  If you ordered a 

wind speed sensor,

 install it on the top of the pole. 

You will find the three-cup wheel and the allen key to fix it to the axis 

of the sensor; if you also ordered the

 wind direction sensor

, you will 

find a ”T” shaped holder with two clamps provided. The wind direc

-

tion sensor should point to north and the wind speed sensor should 
point towards south. Both sensors are sensitive to obstructions and 
turbulence.

Note: 

12 sensors can be connected directly to the iMETOS board; an 

extended set of sensors (up to 600) can be connected via RadioNodes 
or cable chain nodes. There is a connector on the top of the mother-
board for the radio access point. An alternative use of this connector is 

to read up to two soil moisture profile probes or the snow depth sensor. 

For detailed info about the installation of sensors refer to 

metos.at/ime-

tos-3-3-manual 

or the extended manual.

START-UP THE iMETOS 3.3

On GPRS, UTMS, LTE (i.e. G2, G3, G4) networks a SIM card from a provid-
er is required. In CDMA network, you do not need a SIM card. 

To insert the SIM card:

N

S

3. Lock the holder 
by sliding the met-
al lock. 

1. Slide the metal 
part of the SIM card 
holder to unlock it.

2. Place the SIM card into the hold-
er so the gold contacts on the SIM 
face down on the board.

Your device is now up and running. The three LEDs on the motherboard 
will turn on for an instant indication that the station has reset. After 
this, the connection with FieldClimate will start and the LEDs will give 
you information about the communication process (for more details see 

Blinking code and SIM card

 sections on 

metos.at/imetos-3-3-manual

). In 

case you need further support, please contact

.

iMETOS 3.3 is a durable and flexible data logger for all weather con

-

ditions, but if you remove it during the winter months and store in a 
warehouse, please disconnect the battery to avoid discharge.

USE YOUR iMETOS

To see the data from your iMETOS station, you need to register on the 
FieldClimate Dashboard. This provides you with access to your station 
data in graph or table form. FieldClimate also provides a powerful deci-
sion support system for growing your crops (plant protection, irrigation, 
sowing, harvesting, fertilizing).

4. Plug the battery cable (yellow 
circle) into the BAT connector on 
the PCB (red circle). 

Note: 

Check that the PIN request for the SIM is disabled and that you 

have data transfer service enabled.
