All of the resources for getting data from the cow into BigQuery
This folder contains all of the Embedded and C projects that will be flashed to the devices operating on the farm
The Firmware that runs on the 2B Tech PAM device
The Firmware that runs on the Arduino MKR board on the 2B Tech PAM, which provides cellular services
All of the code that has been deployed to GCP
Cloud Functions! These are exposed via an HTTP endpoint that GCP manages for us, and run in response to an HTTP request
When the PAM uploads data, it is first sent to Hologram through their Embedded Socket API. This is a low overhead protocol that minimizes bandwidth from our embedded device. Hologram then sends the data to a webhook that we have defined. In this case, the webhook is this Cloud Function. The Cloud Function simply takes the data sent from Hologram and inserts it into a raw table in BigQuery (sensors_v1.raw_backpack_v1).
Cloud Run Jobs!
This Cloud Run job is triggered nightly be an associated Cloud Scheduled Trigger. The job is responisble for taking the data that was inserted into raw_backpack_v1 during the previous day and inserting it into backpack_data_v1. This second table has a schema that represents the data that was collected, rather than the data that was uploaded to Hologram.
