pyDavis

A package intended the logging of weather data parameters monitored by Davis weather stations. The parameters are obtained through the reports generated at Davis WeatherLink websites, and can be streamed to a MySQL database or a specified file.

To Do

• Checkout scikit-learn tokenizer/lemmization tools for processing of raw HTML data.

Installation

The package can be installed with pip

pip install pydavis

Usage

Through the data_logging.py module, the weather parameters are streamed from WeatherLink websites:

>>> from data_logging import DataLogger

By instantiating the DataLogger with an URL, the logging sequence can then be initiated and data stored according to specified format. Any logging sequence is aborted with CTRL + C.

Storing data in a MySQL database

>>> logger = DataLogger(url)
>>> logger.initiate_logging(
         to_table=True,
         # MySQL username
         user='user',
         # MySQL password
         password='password',
         # Name of existing or new data base (created)
         database='pydavis',
         # Name of existing or new table (create)
         table='weather_data'
     )

The necessary arguments are MySQL login credentials, the name of the database and the table. The logger will create the database and the table if necessary.

Storing data in a file

>>> logger = DataLogger(url)
>>> logger.initiate_logging(
        to_file=True,
        # Name of existing or new file (created) to store
        # parameter values.
        path_to_file='./weather_data.csv'
    )

The location including the name of the file must be passed as argument. The logger will create a new file if necessary.
