Cloud backend infrastructure

DigitalOcean Singapore server running (Linux). Option to switch to Azure (have servers running there as well) for advanced DB storage and ML model integration, but I think we rather want to keep it simple.

Functionality

Currently, a python listener is subscribed to test/#. Upon receiving any incoming messages to the channel, it will insert an entry into the mongodb database under the collection abc, where the test/abc is the published channel.

The current format of the document is as follows:

[
  {
    "time": 5555,
    "temp": 26.0,
    "light": 512,
    "acc": [<x>, <y>, <z>, <g_res>],
    "gyro": [<pitch>, <yaw>, <roll>]
  },
  ...
]

Accessing Database

1. SSH into the droplet
2. mongosh cs3237 -u cs3237 -p thisisag00dp4ssw0rd
3. mongodb commands to select relevant documents
