with

Marvell EZ Connect

and AWS IoT

Objectives

• Introduction
   
• Let's build an application
   
• Analyse the building blocks

Amazon

AWS IoT

• Largest cloud service provider by far, also cheapest
   
• Supports standards like MQTT, ReST
   
• Works great with existing Amazon Web Services

MW302

• Security
   
• Plenty of peripherals
   
• XIP ensures flexible space
   
• Field tested with consumer products like 
  
  - Mattel's Hello Barbie
  - Whirlpool
  - and plenty more

+

LPG Gas Sensor

• Winson flammable gas sensor - MQ6
   
• ADC output
   
• Sparkfun link

Pin Map

source

Cloud setup

• Create a new Thing
   
• Attach a policy
   
• Connect to a physical device - get the private key and certificate

MCU firmware

• Create a uAP
   
• Create a web server to accept private keys and certificates
   
• Connect to the AWS IoT topic that we created 
   
• Get the readings from the ADC - which is connected to the sensor

How it works

source

Add a rule

• Rules are responsible for tying IoT events to other services
   
• SQL-like syntax

Object Store

• Amazon S3
   
• Statically store any type of data
   
• Buckets and objects

Lambda fn

• Execute one off functions in the cloud
   
• Let's tweet !

Push notifications

• Send a notification to a client (usually an email or SMS)

Data streams

• Applications, especially in Industrial IoT, require data from multiple sensor nodes
  
   
• Let's create a bunch of sensors 

Let's map it !

• Real time
   
• BLR traffic *badly* needs this :) !

A connected hardware solution ?
