9. What will be covered in this webinar series
Sense Your Smart City: Connect
Environmental Sensors to SensorThings API
Visualize Your Smart City: Build a Real-Time
Smart City Dashboard for SensorThings API
Analyze Your Smart City: Build Sensor
Analytics with SensorThings API
Build Interoperable Smart City Applications
Effortlessly

10. Today’s learning outcomes
๏ Review of SensorThings entities (ISO 19156 O&M)
๏ Register an environmental sensing device
๏ Publish real-time readings to SensorThings
๏ Arduino environment
๏ LinkIt ONE IoT board
๏ using both HTTP and MQTT

11. Why build your IoT application
with open standards?

12. DISCLAIMER
Today’s webinar is about the underlying API
and data model.
Today’s is NOT about an end-to-end
solution.

13. Let’s say we want to monitor how warm
(or cold) is a certain section of a river.
so we know when
will be a good time
to go rafting.

14. What do you need?
Postman - sending
HTTP requests
+
Hive MQ - receive
MQTT notifications
Arduino IDE +
LinkIt ONE board

15. Steps
Register the
monitoring
device
Device publish
observation
readings
1 2
Receive
notifications
Receive latest
observations

16. prepare the data model
LinkIt ONE
A section of a river
Water Temperature
Probe

A section of a
river

17. How to know a new Thing joining…
Let’s subscribe Thing entities first, so that
we can receive notifications when a new
Thing is created.
Host: scratchpad.sensorup.com
Port: 1883 or 9001
Subscription topic: v1.0/Things

18. Register a Thing
Deep Insert: check out our first webinar series for details
Thing
Location

19. Create a Datastream
Change the id to the
Thing you just created

20. Device Location and Feature of Interest
Feature of Interest
(a polygon)
The target of this sensor is this section of the river.

21. Step 2
Register the
monitoring
device
Device publish
observation

1 2
Receive
notifications
Receive latest
observations

22. Hardware you need
