What a smart city could be like, integrating IoT sensors and scenarios to further enhance the convenience of the city's services for the inhabitants, while improving its energetic efficiency.
This is the repo for everything regarding the Axians's smart city model.
Here is a quick diagram showing every major component of the model :
- Various sensors (temperature, humidity, noise, parking spots..) are connected to Arduinos equipped with LoRa antennas, that transmits to a nearby 4G LoRa gateway.
- Data & management informations are uploaded to our Acklio server.
- Actual sensor data is retrieved by an AWS instance for decoding/storage/visualisation.
Each section below is describing one of those components.
Here is a list of the hardware components used in the smart city model :
- 3 Arduino Uno as micro-controllers, on top of which sits:
- Grove Hat for easy cable management, with the following sensors :
- A LoRaWAN antenna, to upload the gathered data to a nearby gateway,
- A Multitech LoRa gateaway, to receive the payloads from the antenna
Each arduino is responsible for a specific task :
- Arduino 1 is managing the street lamps and monitoring the temperature / noise level of the city,
- Arduino 2 is managing the city's trash cans
- Arduino 3 is managing the parking spots
To manage our devices (gateway, sensors..) and enable 3rd party apps to access our data, we are using Acklio's cloud.
A cloud-based visualisation platform is being used. Running anywhere is a influxDB + Grafana combo for long-term storage & visualisation.
Example of dashboards
it is composed of :
- a python worker that connects to Acklio, decode the payload and stores it into influxDB
- influxDB, a timeseries database for storing the data uploaded by the smart city
- grafana, to visualize the data either in "real" time, or historically.
The code, infrastructure & other components docs are documented in DEVELOP.md.

The LoRa library is GPL, as is whatever code calling it, including the /src dir.
But my lib for the sensors in /lib/sensors is under MIT.
Same goes for the code of the python worker, all MIT.
