Let‘s look back at the origins of how this IoT revolution came about before exploring more on the what, why and how of IoT!

The History and Evolution of IoT

While the last decade saw an explosion of IoT across consumer and industrial use cases, the foundation for connected devices and automation was laid much earlier.

We can trace the origins of IoT all the way back to the industrial revolution in the 18th century which mechanized manufacturing using steam and water power. This kickstarted automated machines enhancing productivity.
The next wave came with the advent of electricity and mass production assembly lines in the early 20th century championed by Henry Ford. This accelerated automation across industries.
The third digital revolution began in the 1970s with early computers and data analytics capabilities, especially in process industries.

Alongside these waves, advancement in communications technology – from the telegraph to telephony and ultimately the internet laid the connectivity foundation to fuel IoT growth.

Finally in 1999, the term Internet of Things was coined by Kevin Ashton to describe systems where the internet connected with physical objects enabling a whole new wave of capabilities.

In the 15+ years since, maturation of networking, sensors and cloud platforms have enabled rapid IoT adoption.

So in essence, IoT represents the culmination of over 250 years of industrial, computing and internet advancements!

Key Takeaway: IoT capabilities bringing together connectivity, automation and analytics have evolved over multiple industrial and technology revolution waves spanning 250+ years.

Let us move ahead to get a better understanding of what IoT is, what it comprises and how it delivers value.

Demystifying Internet of Things

At its simplest definition – the Internet of Things (IoT) refers to a system of interconnected physical objects or devices that can collect and exchange data over the internet.

The “things” in IoT can refer to a wide variety of assets like machines in factories, vehicles, electronic appliances in homes or components of infrastructure like roads or bridges. Embedded sensors in these things connect them to the IoT network.

IoT enables three key capabilities:

Sensing – Collect data like temperature, motion, images etc. with embedded sensors
Communication – Connect with the cloud and other devices over internet
Automation – Take automated actions or trigger alerts based on insights

Together this allows remote monitoring, central data consolidation and autonomous control scenarios from what were previously standlone disconnected physical assets.

Key Takeaway: IoT network connects physical assets to the internet leveraging embedded sensors and connectivity to enable real-time data collection, monitoring and automation.

But how is this actually accomplished? What are the key pieces of the puzzle that comprise an IoT ecosystem?

The Core Pieces Powering IoT Solutions

An IoT ecosystem has 5 major components:

Physical Assets: The core “things” in IoT that connects people, devices or assets requiring connectivity and intelligence. Includes equipment, devices etc. with sensors embedded in them to collect data.
Connectivity: Enables transmission of data from sensors and devices to the cloud over the internet. Can leverage technologies like 2G/3G/4G/5G, WiFi, Bluetooth, LPWAN etc.
Edge Computing Infrastructure: Instead of routing all data to the cloud, real-time insights are processed locally on gateways or devices themselves. Helps overcome latency or connectivity limitations.
Cloud Platforms: Provides scalable and on-demand processing of high velocity sensor data streams with analytics or machine learning capabilities to uncover insights.
Applications: Visualizes meaningful analysis from IoT data and allows users to monitor or control devices. Delivered via web or mobile dashboards or custom software interfaces.

Beyond the core components, an IoT ecosystem also relies on data storage, security layers, device management software, integration middleware and more depending on use case complexity.

Key Takeaway: An IoT architecture has 5 key pieces – devices/assets, connectivity, edge computing, cloud platforms and applications. Additional components can augment the ecosystem for more complex deployments.

Now that we understand the technology powering IoT, let us explore some real-world applications and use cases where IoT is adding tremendous value.
