Provide dashboard, plots for air quality readouts

Air Station

Air station project is the air quality sensor paired with display that aims to:

• monitor the air properties in real time, display it on dashboard,
• provide the explanation pages for user to learn about air quality properties (in future),
• acquire data to show daily graphs (in future),
• provide local web page to read through the readings, dashboards and all using computer or phone (in future)

At now completed:

1. Show in dashboard current readings (dashboard need little polishing but the main objective is completed)

Next to complete:

1. average readouts, tune the cooldown, dashboard tweaks, code refactoring
