A gas sensor array never functions as an independent analytical instrument. It is one of the few essential components of a detector, an analyser, a monitor (the analyser working according to a sampling plan as a function of time) or an automated system for continuous measurements, in real time. For that reason, the sensor array must cooperate with other elements of the analytical equipment ...
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.
