IoT Stats and Facts

Although a revolution in and of itself, the internet has also birthed a large number of other technology revolutions. From smartphones to Wikipedia, the Internet as a medium has resulted in a complete and total transformation of societies worldwide.

Among the most recent developments owing its existence to the internet is the “Internet of Things”, or IoT. This is a new term and concept applied to devices that work together in an interconnected way to gather information, often to better automate processes, and to create a more cohesive and informed user experience.

IoT encompasses a growing number of tech products, including smart home devices like Google Home and the Amazon Alexa-powered Echo, to smart refrigerators that can create grocery lists for you. Most studies and researchers, however, count any internet-connected device as part of the “Internet of Things”.  

From a simple view, IoT is about attempting to connect pretty much everything in the world to the internet in some way. From a technical standpoint, however, the “Internet of Things” can be defined, at least by Cisco, as the “the point in time when more ‘things or objects’ were connected to the Internet than people”. According to Cisco, that point was reached around 2008-2009.

A decade of being immersed in IoT means there are big numbers to show for it. And with more devices connected to the web than people (over 4 billion web users as of 2018), the growth of IoT has produced some surprising data and stats to explore.

IoT at a glance

Considering IoT is primarily about the number of devices connected to the internet, these stats demonstrate how large the Internet of Things has grown.

Industrial, energy, and construction IoT stats

The manufacturing and industrial sectors are early and fast adopters of IoT technology, a trend currently known as Industry 4.0. Industrial Internet of Things (IIoT) has a heavy focus not on people using machines, but on machine automation with minimal human input thanks to robotics.

IoT is set to allow robots to operate more intelligently in the industrial sector, with a move toward greater efficiency and cost savings. Human operated machinery is decreasing in the manufacturing and industrial sector, making automated IoT that requires a decreasing level of human input a large focus.

Meanwhile, construction is experiencing a bit of a slow adoption with new technologies such as IoT. Although technically part of the industrial sector, construction maintains a set of technology needs that set it apart, even as it shares a lot of the same technical challenges as the wider industrial sector.

There’s a lot of attention on how IoT can be used to improve worker safety in construction, which many workers and industry observers openly welcome. Given the construction industry is among the most dangerous for workers, IoT can help set to make it far safer than ever before, so long as businesses in construction are willing to spend the money to make it happen.
