What is the IoT being used for today?

Extend the value of goods and services, e.g.Lock/Unlock/Find your carTell me when my washing is doneHow well am I cleaning my teeth?

Monetize through new business modelsAd-hoc care hirePay-as-you-drive insurance

Optimize by understanding behaviour and anticipating most optimal actions

Technology shift: Consumers lead the Internet of thingsToday Tomorrow Integration

A few connected devices per person…

Almost every device that consumers own will be connected, and many new ones will be created to leverage

the value created by consumer connections.

Cross-platform integrators will

connected devices and automate

personal activity:Door Lock

Dishwasher

Clothes Washer

Clothes Dryer

Window Lock

Garage Door

Toothbrush

Garden Moisture

Coffee Maker

Home Lights

���� Just as consumers have led enterprises in embracing new mobile services, we

believe they will lead the adoption of connected devices & integrated services

IoT use cases have many common requirements

Core Requirements:

� Easily on-board connected “things”

� Create a real-time communication channel with the “thing”

� Begin capturing data from the “thing”

� Visualize data from the “thing”

� Collect data in a historian DB

� Provide access to the collected data

� Manage the “things” and the connectivity to them

� Secure the data from the “thing” and control access to that that data

� Pay for the service based on usage

Extended Requirements:

� Perform analytics both in real-time and on historical trend data

� Trigger events based on specific data conditions

� Interact with the “thing” from business apps and/or from mobile devices

� Send commands to the “thing”

IBM Internet of Things Cloud Quickstart

Key Capabilities:

• Extremely rapid device onboarding

• Real-time collection of data from devices

• Visualization of data from devices

• Communications api to allow custom devices to be added

• Access to data for Bluemix applications via the IoT Service

What Users Can Do:Connect devices, collect, route, and visualize dataBuild internet of things applications to analyze dataCustomize and add further devices

Note: IoT Cloud Quickstart is a tool to let embedded device developers connect to the IoT and see data from their device, and to provide data for IoT application developers to use. It is not intended for production use.

It is a free service, there is no device or user registration step, and all data sent to the Quickstart cloud could potentially be viewed by any internet user.

Methods For Building Applications With the IoT Cloud

Develop applications using MQTT client libraries and runtime of choice (Java, Node, WebSphere, etc) and deploy on premise

Use BlueMix runtime of choice with the Internet of Things service

Use the BlueMix Internet Of Things Boilerplate

12

Sample Application

Our sample application will do the following:

• Collect sensor reading from a device

• Detect when the temperature sensor exceed a given threshold

• Send an SMS to alert the owner

We will build the same application in three way:

• Local NodeJS application communicating with the IoT Service

• BlueMix NodeJS application bound to the IoT Service

• BlueMix Internet of Things Boilerplate which includes Node-RED bound to the IoT Service

For our device, we will use a TI SensorTag with a BeagleBoneBlack gateway

For SMS, we will use Twilio

TI SensorTag Quickstart Visualization

15

Internet Of Things Quickstart Message Format

The UI has predefined visualizations for known messagetypes, but you can supply your own messagetype. The UI delivers a generic visualization for messagetypes that it doesn’t recognize.

The messagetypes known to the UI include:• rpi-quickstart• mbed-quickstart• titag-quickstart

The message payload must be in JSON and conform to the following format. It must not exceed 4096 bytes (that’s the QuickStart limit):

{ "d": { "name1": "stringvalue", "name2": intvalue, ... } }

Here's an example: { "d": { "myName": "Stuart's Pi", "cputemp": 46, "sine": -10, "cpuload", 1.45 } }

"myName" is optional – but if you supply it, it’s displayed as a title on the visualization page.

Building Our App Locally

NodeJS installed locally

Use MQTT and Twilio libraries

• var mqtt = require('mqtt');

• var twilio = require('twilio');

Connect MQTT client to IoT messaging service and subscribe

• client = mqtt.createClient(mqtt_port,mqtt_host, { "clientId": clientId } );

• client.subscribe(topicString);

Implement “on message” handler client.on('message',

function (topic, message)

{

console.log(message);

var payload = JSON.parse(message);

console.log(payload.d.objectTemp);

//check to see if the objectTemp is above 50 degrees

if (payload.d.objectTemp > 50)

{

//send SMS alert

sendSMS(twilioSid,twilioToken,'+1 240 506-8077','It is getting hot in here. Temp is ' + payload.d.objectTemp);

}

}

);

VCAP_SERVICES

Modify Our App To Use VCAP_SERVICES

21

//parse VCAP_SERVICES if running in Bluemix

if (process.env.VCAP_SERVICES)

{

var env = JSON.parse(process.env.VCAP_SERVICES);

//debugging

for (var svcName in env)

{

console.log(svcName);

}

console.log(env);

//find the IoT Service

if (env['InternetOfThings'])

{

iot_props = env['InternetOfThings'][0]['credentials'];

console.log(iot_props.endpoint_host);

console.log(iot_props.endpoint_port);

}

else

{

console.log('You must bind the InternetofThings service to this

application');

}

//find the Twilio service

env['user-provided'].forEach(function(service) {

if (service.name == 'Twilio') {

foundTwilio = true;

twilio_props = service.credentials;

}

});

if(!foundTwilio)

{

console.log('You must bind the Twilio service to this application');

}

}

//mqtt properties

var mqtt_host = (iot_props.endpoint_host ||

'messaging.quickstart.internetofthings.ibmcloud.com');

var mqtt_port = (iot_props.endpoint_port || 1883);

var topic_template = iot_props.topic_template || 'iot-1/d/${device_id}/evt/

${message_type}/json';

//Twilio properties

var twilioSid = (twilio_props.accountSID||'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX');

var twilioToken = (twilio_props.authToken||'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX');
