=Description of the Experiment=
Under construction.

=Experimental Apparatus=
This weather station is installed on the top of [http://www.ist.utl.pt/ Instituto Superior Técnico]'s [http://maps.google.com/maps?daddr=38.736758,-9.139397&hl=en&ll=38.736904,-9.139182&spn=0.00213,0.005284&sll=38.736829,-9.139182&sspn=0.00228,0.005284&t=h&mra=mift&mrsp=1&sz=18&z=18 Central Pavilion], in Lisbon, Portugal. It is permanently recording the data it acquires in a database, averaging the values for each hour. The user can access the data from the last acquisition and the database itself, represented as graphs.

The sensor is a thermistor, i.e. a resistor that varies with temperature. The temperature for a given value in electrical resistance can be found with the following formula (given by the manufacturer):

This sensor was developed by the MERCATOR company, having been placed in a RHU217-AT model board. Operational values are between 0º and 60º (precision $ \pm 0.7 ºC$ at 25ºC).

=Protocol=
First, the user has to select the data to be observed (by default, the latest data is shown).

[[File:Meteo-config1.jpg|thumb]]

Sensor panel:
* Select the type of data to be shown, by choosing which sensor to look at.

Resolution panel:
* Select the time scale for the graphical representation.

Period panel:
* Select the time interval between samples.

Buttons:
* OK - confirm the chosen selections, go to the experiment stage.
* Cancel - close the config window.
* Default config - default selection.
