Description of the Experiment
This experiment allows access to a weather station's database.
Experimental Apparatus
This weather station is installed on top of Instituto Superior Técnico's 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 ±0.7ºC at 25ºC).
Protocol
First, the user has to select the data to be observed (by default, the latest data is shown).
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.
Data Visualization Window After the configuration, the chosen data can be observed. The latest acquisition is always shown and the data from the database is shown graphically.
