The manufacturing industry is on the brink of a revolution with the Internet of Things (IoT). Traditional factories, with their large assembly lines and hum of industrial machines, are evolving into more intelligent, connected, and efficient production facilities.
At the heart of this change is IoT — a network of machines, devices, sensors, and humans that are connected, communicating, and collaborating with each other in real-time. The Internet of Things provides visibility and control over every part of the manufacturing process.
The IoT plays an essential role in today’s manufacturing processes. With IoT our traditional, linear manufacturing landscapes are being transformed into dynamic and intelligent ecosystems faster. Ecosystems that can self-adapt, self-learn, and self-optimize, often with little to no human intervention.
This is a shift that is already producing sizable improvements in productivity and operational efficiency and at the same time opening new channels for innovation and customization that can meet the ever-changing demands of the consumer market at an accelerated pace.
In this blog post, we will examine exactly what IoT in manufacturing means — covering its past, the key technologies involved, and the many ways it’s benefiting the industry.
Evolution of IoT in Manufacturing
The journey of IoT in manufacturing is a tale of technological evolution. Its origins go back decades to the dawn of early automation systems in the 1970s. These early systems were groundbreaking for their time — but they were also limited in what they could do. They couldn’t talk to one another. They couldn’t adapt to changes in conditions.
Fast forward to the 1990s and the internet began to reshape our world. Yet it was still in its infancy in its penetration into manufacturing.
Fast forward into the 21st century, and now IoT has started to take form. Manufacturers began to imagine world of internet-connected devices — machines that could communicate and eliminate downtime; that could predict failures and order their own replacement parts ahead of time; and could adjust production without human hands. This vision was the birthplace of what we today call IoT in manufacturing.
And now we stand at an incredible juncture of time — IoT as reality. Factories from around the world have more sensors, robots, and smart devices than ever. And those are devices that collect and analyze data in real-time. Those are machines making decisions that used to be in the hands of the human on the factory floor.
It’s a monumental shift, because it’s not just automation — it’s smart automation. Machines that predict when they need maintenance, that adjust to unknown changes in production demand, or even manage the inventory themselves.
