Build an Air Quality Monitor with InfluxDB, Grafana and Docker on a Raspberry Pi
Measuring a sensor is so complicated...Influx, Grafana and Docker is not enough. You may want to throw in AWS, some Google API and not to forget: Tensorflow. A pinch of opencv with GPU support might make it real software. Cross compile all this for windows that runs on RPi so corporate clients can trust it -- because buying a license always reflects seriousness.
