Read Raspberry Pi Computing: Gas Sensors | Leanpub

We’ve assembled our Raspberry Pi with a gas sensor and an analog to digital converter. We installed an operating system and configured it for use. We’ve set up networking and installed a database and a web server. We’ve written code to record data into our database and an API to pull data out of it. We’ve even installed a graph to display it in a visual form. Nice work.
