Librarians were the original data nerds, so they jumped when we talked about sensor data acquisition on Twitter. We created another one of our Pi-based environmental sensor systems, and sent it over to the library for deployment.
The library dashboard was online and allowed you to watch the cool and refreshing environment they enj… have to keep their books in.
We ran this on Node-red again, and visualising the data from a Heroku instance. Deployment to the library was a matter of plugging in and adding a network cable, and much of our codebase and infrastructure for this was simply copy-and-paste with minor changes to the CloudMQTT endpoints and configuring the interfaces in the Heroku-hosted machine.
Because we’re gluttons for punishment, we also put together a quick dashboard overlaying our key metrics. Try to guess who’s in the air-conditioned space and who’s in the glass tank!
