The infrastructure behind Air Quality Web

For a while now, I've been working on Air-Quality-Web, a web interface that displays air quality information. While I haven't blogged about it directly before, a number of posts (a, b, c, d) I've made here have been indirectly related.

Since the air quality data has to come from somewhere, I thought I'd blog a little about the wider infrastructure behind the air quality web interface. My web interface is actually just 1 small part of a much wider stack of software that's being developed as a group by Connected Humber.

Said stack is actually quite distributed, so let's start with a diagram:

From left to right:

We can represent the flow of data here in a flowchart, to get a better idea as to how it all fits together:

As you can see, there are many areas of the project that can be worked on independently of each other - depending on what people feel most comfortable working on. Personally, I stick mainly to the HTTP API and the main web interface with a hand in advising on database design, but there are lots of other ways to get involved if you so choose!

Sensors always need building, designing, and programming, and the data generated is available via the public HTTP API (the docs for which can be found here) - so anyone can write their own application on top of the data collected by our sensors. Want a light on your desk (or even your hat) that changes colour depending on your local air quality? Go ahead!
