Sensors Sensors Everywhere

A sensor is anything that can create data about its environs. A more formal definition is

a device that detects or measures a physical property and records, indicates, or otherwise responds to it -New Oxford American Dictionary

A very simple example is a thermocouple.

Essentially, two metals are bound together such that when the environment around this wire becomes hotter or colder, the metals produce a voltage. Through this thermoelectric effect, this strain translate into a voltage differential across the wire, producing an electrical signal. A simple voltmeter can read this signal, and one could calibrate that electrical signal to be read as degrees of temperature change.

You likely have one of these in your home thermostat. Perhaps you have a very simple thermostat that turns your home heater on and off.

Perhaps you have a more complex, programmable thermostat that can control the temperature and humidity of your home through a furnace, air conditioner, humidifier/dehumidifier and fans, with different settings for different times of the day and days of the week.

Perhaps you have something that looks very simple, but is now part of a complex system that includes not only your home HVAC system, but your computer and smartphone, and computers and analytic software at your utility company.

And this progression is why the Internet of Things is about to explode with Connected Data, with sensors being the new nerve endings of an increasingly intelligent world.

This is a section of my Internet of Things mindmap showing just the sensor branches.

Imagine sensors streaming Connected Data from your home entertainment system, refrigerator & most of its contents, toaster, coffee maker, alarm clock, garden, irrigation, home security, parking on the street in front of your home, traffic flowing by your home to your destination, air quality, and so much more.

We will interact with the world around us in ways that will change our decision making processes in our personal lives, in business, and in the regulatory processes of governments.

The Internet of Things and Change

Will You Be Ready For the M2M World?

The Internet of Things, the Connected World, the Smart Planet… All these terms indicate that the number of devices connected to, communicating through, and building relationships on the Internet has exceeded the number of humans using the Internet. But what does this really mean? Is it about the number of devices, and what devices? Is it about the data, so much data, so fast, so disparate, that will make current big data look like teeny-weeny data?

I think that it's about change: the way we live our lives, the way we conduct business, the way we walk down a street, drive a car, or think about relationships. All will change over the next decade:

  1. Sensors are everywhere. The camera at the traffic light and overseeing the freeway; those are sensors. That new bump in the parking space and new box on the street lamp; those are sensors. From listening for gun shots to monitoring a chicken coop, sensors are cropping up in every area of your life.
  2. Machine to Machine [M2M] relationships will generate connected data that will affect every aspect of your life. Connected Data will be used to fine-tune predictives that will prevent crimes, anticipate your next purchase and take over control of your car to avoid traffic jams. The nascent form of this is already happening: Los Angeles and Santa Cruz police are using PredPol to predict & prevent crimes, location aware ads popping up in your favorite smartphone apps, and Nevada and California are giving driver licenses to robotic cars.
  3. Sustainability isn't about saving the planet, it's about saving money. Saving the planet, reducing dependence on polluting energy sources and reducing waste in landfills are all good things, but they aren't part of the fiduciary responsibilities of most executives. However, Smart Buildings, recycling & composting, and Green IT all increase a company's bottom line and that does fall under every executive's fiduciary goals.

Making Sense of Inter-Connectedness - Introducing My Internet of Things Mind Map

As you can tell from the mindmap associated with this post, I've been thinking about the Internet of things quite a bit lately. It's a natural progression for me. I'm fascinated by all the new sensors, the Connected Data [you heard it here first] that will swamp Big Data, the advances in data management and analytics that will be needed, the impact upon policy and regulation, and the vision of the people and companies bringing about the Internet of Things. But more, as I've been reading and thinking about the SmartPlanet, SmartCities, SmartGrid and SmartPhones, and that ConnectedData, I realized that I can never look at the world around me in the same way again.

Let's look at some of the "facts" [read guesses] that have been written about the IoT.

Looking to the future, Cisco IBSG predicts there will be 25 billion devices connected to the Internet by 2015 and 50 billion by 2020. From The Internet of Things: How the Next Evolution of the Internet Is Changing Everything by Dave Evans, April 2011 [links to PDF]

Between 2011 and 2020 the number of connected devices globally will grow from 9 billion to 24 billion as the benefit of connecting more and varied devices is realised. The Connected Life: A USD4.5 trillion global impact in 2020, [links to PDF] February 2012 by Machine Research for the GSMA.

Two different estimates, one of 24 billion devices of many different types, connected by wireless broadband, and one of 50 billion mobile devices using different types of cellular networks, all by the year 2020. And neither of these estimates include the trillions of other types of things that will deployed over the next eight years. Trillions, not billions, using a variety of personal, local, and wide-area wireless networks.

My Focus Starts at The Intersection of Sensors, Analytics and Smart Cities, with Energy Management and Sustainability

One of the things that will change over time is the way that I look at the Internet of Things. All of it is interesting. But for now, I'll be focusing on the intersection of Sensors, Analytics and Smart Cities, with Energy Management and Sustainability.

Count RFID, Zigbee, MEMS, Smartdust and more traditional sensors, Robots, autonomous vehicles, Healthcare monitors, Smart Meters and more, being distributed in cities, cars, factories, trains, farms, planes, animals and people, and the number of connected devices in 2020 will be in the trillions. Data generated by less than one billion humans using the Internet a few times a day swamped traditional data management & analytics systems, spawning "Big Data". Trillions of devices updating ConnectedData every few nanoseconds will indeed change everything.

Of paramount importance moving forward is determining how to extract business, personal and social value from the intersections, interfaces and interstices of the infrastructure, connected data, objects and people building relationships through the Internet of Things.

Come join me as I look at this convergence and the business impact ahead of us.

The TeleInterActive Lifestyle is about the business processes, life choices, management challenges and technical issues facing organizations and individuals as individuals and organizations adopt the Internet of Things, Mixed Reality, wireless networks of all levels, mobile devices, long-distance collaboration, social networks, digital transformation, and adjust to growing urbanization.

Sensor Analytics Ecosystems for the Internet of Things (SAEIoT) brings value from emerging technologies through data management and analytics, advances in data science, as the IoT matures through the 5Cs: Connection, Communication, Contextualization, Collaboration and Cognition. The socialization of machines will allow for Privacy, Transparency, Security and Convenience to be flexibly provided with two-way accountability to build Trust among Humans and Machines.

AsDataArchon, we have evolved our consulting data scientist work from learning how to incorporate sensor analytics into data warehouses, business intelligence and analytics to focusing on IoT data management and forming sensor analytics ecosystems.
