We hooked up a simple particle sensor to an Arduino that was able to communicate its sensor values to TTN using an RN2483.
A separate process forwards the incoming data to a Firebase database, ultimately resulting in https://aelora.nl where we monitor our air quality.
All components were neatly packaged inside a beautiful bird-like form factor, much nicer for the unsuspecting passer-by to look at. Can you spot the antenna ?
