A Krawler based service to download data from WeatherLink V2 API
The k-Weatherlink jobs allow to scrape all sort of data from sensors connected to stations. The data are stored in a MongoDB database and more precisely in 2 collections:
- the
observationscollection stores the observed data from the sensors, more information here - the
stationscollection stores the data of the stations
The project consists in 2 jobs:
- the
stationsjob scrapes the stations data associated to your account, according a specific cron expression. By default every day at midnight. - the
observationsjob scrapes the last (current) observation of the stations above according a specific cron expression. By default every 5 minutes.
The data retrieved and frequence at wich they are retrieved are limited by your relationship with the station and subscription, see more here.
