IoT Applications based on LoRaWan

0.3-22 kbps2-3 km in urban areas,6-10 km in rural areas
A battery can live 3 years, while sending every 5
minutes
What is LoRaWan?Low-Power Wide-Area Network (LPWAN) or Low-Power Network (LPN) is a unlicensed wireless telecommunication network designed to allow long range communications at a low bit rate among low power things (connected objects), such as sensors operated on a battery.[1][2]
This allows for long-lived & cheap sensors, which cost ~ 25 EUR.Suitable where Wifi, Bluetooth or *G networks are not available.
What is the TheThingsNetwork?A Layer on top of LoRaWan, which allows your application to work with sensors without needing to worry about the infrastructure.• Consists of
Nodes, Gateways & the backend
How can you interact with it?• You receive your data encoded in JSON (TTN helps with decoding data
into JSON)• You can subscribe to incoming data via MQTT/HTTP Push.• There is an API to even send data back to the sensors (turning them
into actors as well)• SAP IoT can consume data from TheThingsNetwork. ( see
https://github.com/SAP/iot-starterkit/tree/master/src/examples/java/com.sap.iot.starterkit.mqtt.ingest )
Our motivation: how would it be, if… If citizen could easily support data collection about their own living environment, such as
ozone, fine dust, traffic or noise in the city? Active & constructive participation options
If everybody can get help with building his/her sensors? Use the maker culture to foster understanding of technology
If everybody could learn to process his own data? Show people, how they can make use of big data & algorithms
If this results in public open data sets
Demand data-driven decisions
How do we start?• We‘ll establish a regular IoT workshop in a local makerspace.
• We want to capture real-time data, which influence quality of living.• We aim towards a group of sensors, which everybody can build on
his/her own.(which send standardized data with repeatable quality)• This will be consolidated & interpreted in an Index on Quality of
Living.• This index can be enriched with data from open data sets.
Takeaways for your public IoT effort• Don‘t focus on technology & infrastructure, but treat it as a side activity
look for a practical usecases, knowing that other usecases will follow
• Try to get validation of your efforts from experts avoid to spread just numbers, which can be easily neglected
• Find a local issue in the beginning, which allows you to get inital attention
• Find partners! (e.g. a makerspace, sponsors, research partners)
Thank you for your attention!
