This is the project that encompasses the firmware for the CO2-Sensors of the Friedrich-List-Schule. This is a mint project created by students to detect bad air in the school rooms and ensure that the windows are opened regularly.

Documentation: GitHub Wiki

To build the project, go into the webserver directory and run:

npm run build

To start the project, run the following in the same directory:

npm run start

Running the project in development mode has a few performance deficits. The advantage is that things will automatically refresh when files are changed. To achieve this, we run a vue development server, by running the following command in the webinterface directory:

npm run dev

We also need to startup the webserver as the backend though, so that the api is available. This is achieved by running the same command in the webserver folder in a separate terminal as well. The full development webserver will then be available at localhost:3080. DO NOT USE PORT 8080, since vue is in static mode there.

The CO2-Sensors are implemented through CO2-Sensors hooked up to small arduino boards. Their data is shared through mqtt over w-lan. The data is received by a Node-RED server and stored in influxDB. Prupose of the webinterface is to display the data and make settings. The webinterface is based on vue, vue-bootstrap, express and nodejs. Settings are broadcasted to the arduinos through mqtt directly.
