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

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

Why build your IoT application with open standards?

DISCLAIMER

Today’s webinar is about the underlying API and data model.

Today’s is NOT about an end-to-end solution.

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.

What do you need?

Postman - sending HTTP requests

+

Hive MQ - receive MQTT notifications

Arduino IDE + LinkIt ONE board

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.
