LECTURE L17INTERNET OF THINGS

“Some have suggested that the internet of things “changes everything,” but that is a dangerous

oversimplification.”

- Michael E. Porter & James E. Heppelmann

Radio Frequency Identification

ObjectReader

The idea of using sensors to communication with objects started as soon as Radio Frequency became understood and harnessed

Classifying Sensors

By what you measure (measured)

By how you measure directly:

Acoustic signal strength, or chemical concentration, or optical signal, or magnetic strength

Medical displacement or voltage or chemical reaction

By transduction for indirect measurementMedical displacement or voltage or chemical reaction

By higher level functionSensing ID or human gesture or explosive material

Sensor Modality

Static time-series: temperature

2D arrays: imaging in electro optical (light) or infrared

3D sensing: Kinect, or radar

Mobile sensors: Your phone

Scanning sensors: Google Street View

Fiducial sensing: Homing beacons

RFID - Radio Frequency Identification

RFID is a Radio Frequency sensing of fiducial ID RFID tags, with static or moblie application

Radio Frequency IdentificationIdentifying objects by using radio frequency started early

RFID Application

The average U.S. household has 300,000 things, from paper clips to ironing boards.

The Shortening Waves

Connecting Products

IT is now integral part of the product themselves

Embedded sensors, processors, software, and connectivity in products, coupled with a product cloud in which product data is stored and analyzed and some applications are run, are driving dramatic improvements in product functionality and performance.

The Impact of the Smartphone

Smartphone revolution starts 2007

Contains multiple of sensors

Barometer to sense air pressure and relative elevationAccelerometer to measure distance by walking or runningGyroscope to measure orientation

Information spillover

Processors and sensors

Processors and sensors are now widely available and cheap

Examples Raspberry pi computer, Arduino

By 2020 a cumulative 100 billion processorswill have been shipped, each capable of processing information and communicating

Things get connected

Physical components comprise the product’s mechanical and electrical parts

Smart components comprise the sensors, microprocessors, data storage, controls, software, and, typically, an embedded operating system and enhanced user interface

Connectivity components comprise the ports, antennae, and protocols enabling wired or wireless connections with the product

Smart Connected Things

Connectivity takes three forms, which can be present together:

One-to-one: An individual product connects to the user, the manufacturer, or another product through a port or other interface

One-to-many: A central system is continuously or intermittently connected to many products simultaneously

Many-to-many: Multiple products connect to many other types of products and often also to external data sources

The New Technology Stack

Smart, connected products require companies to build and support an entirely new technology infrastructure

What Can Smart, Connected Products Do?


Monitoring

Smart, connected products enable the comprehensive monitoring of a product’s condition, operation, and external environment through sensors and external data sources

Source: HBR

Example: Glucose Monitor that connects to your smartphone


Control

Smart, connected products can be controlled through remote commands or algorithms that are built into the device or reside in the product cloud

Source: HBR

Example: Lockitron door lock


Optimization

The rich flow of monitoring data from smart, connected products, coupled with the capacity to control product operation, allows companies to optimize product performance in numerous ways, many of which have not been previously possible

Autonomy

Monitoring, control, and optimization capabilities combine to allow smart, connected products to achieve a previously unattainable level of autonomy.

Smart Everything

Smart Everything - what does this mean

Traditionally we use computer to use software - we control the software and tell it what to do and when

Now software is becoming aware of our actiona through sensors, speech and touch

Software is controlling us in real time

Smart Everything - what does this mean

This smartness can be for us as an individual helping us, making our life easier and more productive

This smartness can also help group of people - a whole city to become more efficient
