The corresponding twitter auth data should be put in auth_info.json in the project root with the corresponding names (found in server.py) for the values. The template for the auth_info.json can be found in the project root as auth_info.json.example. Also, this project requires a lot of refactoring to be done, it was a semester project done for a particular course and is relatively crude. The sensor used in this project is the ESP sensor so do check that docs as well. Please refer this link for more info regarding the tweepy API!
