“Alexa, start my evening.” At the command of your voice, the living room lights dim, the music starts, and you’re ready to relax.
Welcome to the world of IoT, or the Internet of Things. However, Alexa and other digital assistants only offer a tiny peek inside that world. IoT is not limited to simple home convenience and automation tasks.
The Internet of Things bridges the material and digital world. Powered by wirelessly networked hardware devices and sensors, IoT technology transmits data, monitors information, and initiates actions in physical systems.
IoT’s power, versatility, and possibility range from the lightbulbs, coffeemakers, and thermostats in our homes to the cities, cars, airplanes, factories, and energy grids that build, move, and power our economy.
The Internet of Things is the physical manifestation of the information economy. It is on the front line of a new industrial revolution.
Industry 4.0: Big Data and the Internet of Things
We typically speak of the industrial revolution as if there has only been one. Industrial technology has continually evolved since coal-fired boilers powered the first steam engines. Sometimes that evolution is a revolution, transforming societies and economies, from steam to electricity, computers and integrated circuits to big data, sensors, and networks.
From Steam to Data: Driving Value
Today, we are well into our third revolution and stepping headlong into the fourth: Industry 4.0. Powering this new industrial revolution is data and what we can now do with it in the real world, in real-time.
“Artificial intelligence, machine learning, big data, and data science enable the benefits promised by IoT,” says Chris Healey, an adjunct professor in data science and analytics at Merrimack College.
The intersection of these technologies, coupled with an expanding web of IoT sensors and edge computing, portend a “technological revolution that will fundamentally alter the way we live, work, and relate to one another,” writes Klaus Schwab in a World Economic Forum article. “The possibilities of billions of people connected by mobile devices, with unprecedented processing power, storage capacity, and access to knowledge, are unlimited.”
We must temper Schwab’s breathless optimism with an understanding of the challenges to such possibility and promise. Acquiring data from a widening circle of inputs does not effortlessly translate to benefit. For that, we need competent, well-trained data scientists to lead the way. Professionals who are skilled in the technology, aware of its ethical implications, and adept at aiding collaborative decision-making among stakeholders.
“Because of the vast amount of IoT data available, there is no way that standard data warehousing, engineering, and processing best practices can be utilized,” Healey says. “We have to use data science and machine learning to translate these data streams into value.”
Benefits and Applications of IoT
IoT changes how we use and interact with everyday objects. “IoT devices provide the link between devices, humans, and the cloud,” says Healey.
“While there are interesting applications of IoT everywhere, I think most of the best applications exist where computing is already closely coupled with the application. Many opportunities with IoT lie in wearable health, autonomous vehicles, the smart grid, and industrial automation.” Let’s take a quick look at each.
We’ll examine the potential of IoT and why the “staggering amount of data” in IoT applications “require new technologies to transmit, store, and process data.”
Wearable Health
In 2021, the global wearable health devices market reached a valuation of nearly $19 billion. Projections suggest a compound annual growth rate (CAGR) of 22.2% starting in 2022, reaching a market cap of $60.55 billion by 2027.
Wearable health includes devices that monitor blood pressure, EMG temperature, blood glucose, , and oxygen level. If that sounds a lot like your smartwatch, you’d be right.
But wearable health extends to critical real-time monitoring for chronic illnesses. Devices either worn, implanted in the body, or attached to clothing monitor heart disease, diabetes, and neurological disorders.
“Wearables are revolutionizing the doctor-patient relationship by providing information about how you feel that enables data-driven, actionable treatment,” writes Sandeep Ozarde on LinkedIn. “Wearables can also enable patients to better engage in self-care and the healthcare ecosystem.”
The Smart Grid
There is arguably no other IoT application more consequential to our long-term prosperity than the smart grid.
“The Smart Grid is a unique chance to transform the energy sector into a new age of dependability, availability, and efficiency, which will contribute to our economic and environmental health.” states an article in Security Boulevard.
The smart grid, renewable energy sources, and energy storage capacity are fundamental to this new energy economy. The Internet of Things controls, monitors, and maintains the smart grid. IoT devices respond to external environmental inputs, balancing loads, and increasing efficiency.
In short, IoT is critical for scaling up a smart, clean, and resilient energy grid.
Industrial Automation
Like everything else listed here, the Internet of Things is an essential ingredient for the future of industrial automation. When harnessed with AI and machine learning, IoT “builds on progress made during the third industrial revolution that sparked the adoption of computers and automation,” says Guy Yehiav in Forbes.
From the factory floor to the global supply chain, embedding connected sensors across a production chain is like digital grease on the wheel of industry.
Smart industrial automation “increases reliability, provides predictive maintenance analysis, reduces operating costs, detects human errors, and determines root-cause errors,” Merrimack College’s Chris Healey explains.
Autonomous Vehicles
Self-driving cars are the poster child of industrial automation and IoT applications. The automotive IoT market was valued at $8.7 billion in 2021. Projections forecast a CAGR of 25.5% with revenue of $286.8 by the end of 2028.
The benefits and potential of IoT apply to commercial and private ground transportation applications. Automotive IoT transforms how we move on our roads and highways– from self-driving applications to safety, navigation, predictive maintenance, vehicle security, and fleet management.
