The document presents a project on a private telemetry and alert system for monitoring flue smoke and gas emissions in smart cities, highlighting its importance for public safety and pollution control. It discusses the use of IoT devices, such as gas sensors and Lora technology, for detecting air quality and gas leaks, along with a public database for data analysis. Key features include wireless notification systems, easy installation, and integration with big data analytics for city monitoring.

3. FLUE Smoke and Gas Certification
- One check at year for gas boiler
- Two times for GPL and solid fuels
- Costs: from 50 to 80 Euro
- Necessity to be onplace

4. Boiler and Flue checks are necessary for…
- Correct working
- Fuel Consumption
- Air quality
- Private and Public Safety

6. Infact, the
Accidents
Reasons
Absence of Smog relevations detector
(29% of accidents)
Malfunctions of Devices
(27% of accidents)
GPL incorrect use procedures
(31% of accidents)
GPL absence of manteinance
(3% of accidents)

7. More…
Pollutions
Problem
Gas boilers, stove, fireplaces principal
contribute to pollutions
(60% of total pollutions in the air)
PM10 grown from 14.000 to 21.000 tons
(ISPRA pollution report 2016)
PM10 by cars reduced from 13 to 5.5
(ISPRA pollution report 2016)
Difficult to individuate immediately
a malfunctions, the source of smog

18. Gas sensor detect out of range data from enviroment
Immediately send an alert through LORA network
1) Gas Sensor device with LORA transmitter

19. Gas Sensor: MQ-135
• Wide detecting scope and fast response and High sensitivity
• Stable and long life Simple drive circuit
• They are used in air quality control equipment for buildings/offices and are
suitable for detecting of NH3, NOx, alcohol, Benzene, smoke, CO2.

22. 2) LORA Gateway: DRAGINO LG01-S
- Very economic… but there are better choices!
- Is only single band!
- LoRa band available at 433/868/915/920 Mhz
- Max range in LoRa : 5 ~ 10km
- Low power consuption
- Multiuser

23. Dragino Configuration
Connecting Dragino with The Things Network

24. Dragino problem: a bad antenna connector!
We have to repair it!

25. The Things Network – Register Gateway
1) Create new gateway
2) Get Gateway EUI
3) Put Gateway EUI in Dragino

26. The Things Network - Application
1) Create application LoraTest
2) Get Application ID
3) Payload decoder

27. The Things Network - Devices
- Application is the hub for one
or more devices
- Device report the address of
phisical transmitter device
- There are two different methods:
APB and OTAA

28. The Things Network: Activation Notes
Over-the-Air Activation (OTAA)
Over-the-Air Activation (OTAA) is the preferred and most secure way to connect with The Things
Network. Devices perform a join-procedure with the network, during which a dynamic DevAddr is
assigned and security keys are negotiated with the device.
Activation by Personalization (ABP)
In some cases you might need to hardcode the DevAddr as well as the security keys in the device. This
means activating a device by personalization (ABP). This strategy might seem simpler, because you
skip the join procedure, but it has some downsides related to security

29. Elastic Search
- It’s a very powerful search engine
developed In JAVA
- Schema free JSON documents,
scalable and real-time search
- Kibana is a visualizations and
presentation Tool for Elastic Search

30. The Things Network – HTTP Integration
- TTN has several plugins to connect
with external services
- HTTP integration sends data in
JSON format to an endpoint
- Here we have to put the URL
endpoint of Elastic Search
(very carefully to create it!)

31. Elastic Search – API Console
- Through API Console is possible
interact with Elastic
- PUT, POST, GET, DELETE
cURL symilar syntax
- A simple GET indices search
to see if everything goes fine

32. Elastic Search - Kibana
- Add an index to Kibana
- Select which Time type do
you want get as reference
- Start your visualization graph

33. Elastic Search - Kibana
- Several type of visualizations
in real time
- Discover: to see immediately
our data
- Visualize: to create interactive
dashboards

34. AWS – DynamoDB
- NoSQL database service that
supports key-value and
document data structures
- Each partition 10GB, 1000 Write
Capacity Units and 3000 Read
Capacity Units.
- Distributed System

35. AWS – DynamoDB
- Integration of AWS IoT with
DynamoDB
- Security policy of AWS
- Stores the received message on
DynamoDB

36. AWS – DynamoDB - RestFul
- Additional: Python (.NET) code to
RestFul
- PUT, POST, GET, DELETE
cURL symilar syntax
- Return all devices and all
value stored

37. AWS – DynamoDB
- Creation of DynamoDB for
records Public Administration
Data
- Restful request in a HTML page
- Georeferencing view of sensors

38. AWS– Android
- Creations of republish of message
- Filter important messages

39. AWS– Android
- Android application for notification
- Using service android for
run in background
- Simple and expandible

40. AWS– Android
- Example of notification
- Very fast

41. POSSIBLE EXPANSIONS
Street gas leaks, hospital air pipes, enviroment at risk…
GAS TANK GAS BOILER GAS STREET PIPES

42. Previous Research
- 2013 publication
- Based on a ZigBee
(100 meters)
- Similar to BT or WI-FI
