Pull request done (#51)

If this pull request is merged successfully this issue will be closed. However, if is decided to include the contents developed in this issue in the main project this issue would be reopened. In order to complete this inclusion some indicative tasks are detailed:

• [ ] Move the crontab process from local to remote Nowadays, there is a crontab process hosted in local that update the sensors stored 'aqi'(air quality index) measure data. More technically runs the script extraction_routine.py thrice a day. It would be needed to host that on AWS EC2.
• [ ] From JSON to DB In the issue resolving proposal all the data is saved in JSON files simulating our document-based data base. It would be necessary to create the new documents needed since this proposal and change the JSON reading/writing functions to DB connections to the new and existent documents.

NEW TASKS: Feel free to add more inclusion tasks which you think that have been forgotten. Thanks! :neckbeard:
