5. Digital Transformation
IPT - USP partnership
Use of Helix Sandbox (Powered by Fiware) for
two proof of concepts in IPT’s Smart Cities
projects:
• Air pollution monitoring
Monitors and traces air pollution maps of
São Paulo's streets.
• Barulhômetro
Monitors and makes the citizens aware of
noise pollution

6. Current solution:
• IoT device installed above
the roof of some public
buses in São Paulo.
• Monitors
• CO2
• CO
• O3
• NO2
• Temperature
• Humidity
• Atmospheric pressure
• Data geolocation

8. Dashboard for air-pollution monitoring – real time and historical data

9. Dashboard for air-pollution monitoring – real time and historical data

10. Current solution:
• LED panels that shows the noise
to the population in loco
• Data are sent to a central server,
which redirects them to website
clients, in real time
• Website
• historical data, aggregated by
minute using a specific statics
method
• Informs curiosities and
information about noise
pollution

12. IPT Connector
Interacts with Helix Sandbox for real-time and
historical data
• Developed in Node.js
• Uses WebSocket for real time communications
• Uses two web services for historical data:
1. Receives POST messages from Fiware
ORION and redirects them to
the WebSocket clients
2. Receives GET requests from the clients,
query MongoDb by the data, execute
statistical calculations, and respond the
historical results to the clients
