• Agriculture

AWS IoT Features Overview

• IoT Framework for the Cloud

• Provides Secure Bi-directional communication between Device and AWS Services

• Provides a scalable solution to collect, analyze and take action based on device telemetry

• Provides an easy way to develop end user applications to control connected devices.

Benefits• Ease of configuration

• Security

• Authentication & Authorization

• Scalibility & Reliability

• Integration with AWS ecosystem

• Logging - Cloudwatch

• Cost

Components of AWS IoT• IoT Device Gateway

• Message Broker

• Things Registry

• Policy & Certificates

• Thing Shadow

• Rules Engine

• AWS IoT SDK

All about Things• Thing

– A Thing is a cloud representation of a single device/hub.

– A Thing can have 3 attributes attached to it.

• Thing type

– A representation of a device type.

– Thing attached to a thing type can have 50 attributes

– A thing can only have 1 thing type and a thing type can have many things associated to it.

All about Things – Cont’d• Thing Registry

– A searchable collection of things.

– Exposed to AWS CLI and API.

• Thing Shadow

– A JSON document of the current and desired state of the thing

– Each thing maintains a shadow.

– When the current and desired states are different from each other an MQTT message is triggered to the shadow topic.

– Applications can retrieve current state and set desired device state.

AWS IoT – Message Broker• Protocols

– MQTT

• MQTT version 3.1.1

• Supports QoS 0 or 1

• Device Shadow is also a Topic

– REST API

• Only message publishing is supported

– MQTT over Websockets

• wss://<endpoint>.iot.<region>.amazonaws.com/mqtt

AWS IoT – Rule Engine• Rules are analyzed on the MQTT Topic Stream.

• Uses an SQL-Like syntax to process MQTT messages

• Actions are performed based on the outcome of the rules.

• A single rule can have multiple actions attached to it.

• Actions have necessary AWS Service policy attached to it.

• Rules & Actions interact with other AWS services like S3, SNS, SQS, Lambda, DynamoDB, Kinesis & Cloudwatch.

Integration with other AWS• Lambda

• DynamoDB

• SNS

• SQS

• S3

• Cloudwatch (alarm & metrics)

• Kinesis

• Amazon Elasticsearch Service

Demo use case overview• Setting up AWS IoT offering using vanilla Raspberry Pi.

• Integrate with other AWS services to start consuming data.

• Will be demoing the data being consumed by S3, SQS, DynamoDB, SNS and Lambda

• Setting up the device shadow with the current temperature and luminosity data

• Sending a message back to the buzzer on the device based on touch input.

AWS Services used for demo

• AWS IoT

• DynamoDB

• Lambda

• S3

• SNS

• SQS
