@NicolasCaspari - pressureless assignment ;)

[erget]

1. Script that can interact with Django layer for saving observations in database
2. Have script read sensor observations (located in /dev) and save them in Observation objects that go into the DB
3. Cronjob that keeps this happening every hour (or other test period that you choose)
