How to install the gO Measurement-System
In the following the correct installation and putting into service of the system is explained.
1.
Setting-up of the base station
1.
Place the base station inside the building/object where you would like to do the measurements, at a location with
good GSM network connection. We strongly recommend plugging in the power supply during the measurement,
since base station battery life is 2
–
3 days.
2.
Turn on the base station by pressing and holding the «power» button until the cloud connection indicator starts to
flash. When pressing the «power» button only shortly the battery charging status can be seen. Please refer to
section
4.2.1 Dashboard,
to check the signal strength of the cellular (2G/3G) base station. Generally, the signal
strength should be above 50%.
2.
Installation and startup of the nodes.
2.1
Inside Node (Type 1):
1.
Mount the node to the wall using min. 3 of the provided double-sided adhesive tapes or place it on a
suitable spot next to the wall (for example a shelve). Make sure, that the adhesive tape strips stick out
under the measurement node (see Fig 2)
2.
Mount the combined heat flux/surface temperature sensor with two double-sided adhesive tapes. Make
sure the red side of the pad is facing the sensor, while the black side must face the wall. It is also
important, that the two strips point to the side of the sensor and not to the direction of the sensor cable
(see Fig. 2).
3.
Mount the ambient air temperature sensor using the provided sensor clip and one double-sided adhesive
tape.
4.
Turn on the node by holding the power button until the connection indicator starts to flash yellow. The
node now automatically builds up a connection to the base station, which can take up to 2-3 minutes. As
soon as the connection is established, the indicators color changes from yellow to green. When the
power-button is pressed shortly the battery charging status ca
n be seen. If the node shouldn’t connect to
the base station within 5min, the node should be restarted and/or relocated. Please refer to section
4.2.1
Dashboard
, to check the signal strength between the node and the base station. Generally, if the signal
quality is below 25% data might get lost.
2.2
(Outside) Node (Type 2):
1.
Mount the node at the wall with min. 3 double-sided adhesive tapes or place it one suitable spot nearby
the wall (for example a window sill).
2.
Mount the surface temperature sensor at the wall with two double-sided adhesive tapes. Note that the
red side of the pad is the “sensor
-
side”, while the black side should face the wall. It is also important,
that
the two strips point to the side of the sensor and not to the direction of the sensor cable (see Fig. 2).
3.
Mount the ambient air temperature sensor with the enclosed sensor clip and one double-sided adhesive
tape.
4.
Turn on the node by holding the power button until the connection indicator starts to flash yellow. The
node now automatically builds up a connection to the base station, which can take up to 2-3 minutes. As
soon as the connection is established, the indicators color changes from yellow to green. When the power
button is pressed shortly the battery charging status can be seen.
If the node shouldn’t
connect to the
base station within 5min, the node should be restarted and/or relocated.
2.3
Additional nodes can be added by repeating step 2.1 and 2.2. Note that it is also possible to connect multiple
inside nodes with one outside node, as long as the outside conditions can be assumed to be the same for both
measuring spots (for example when measuring two U-values next to each other). It is then however only possible
to assess a U-value and no additional R-value since the exact surface temperature of the outside wall is missing.
2.4
Humidity Measurements (Type 3)
1.
Place the node at the spot where you would like to measure the humidity (normally in the middle of the
room).
