What is IoT Technology?

It is widely believed that the internet is the best and most disruptive innovation of the 21st century. This belief is, to a large extent, uncontested, however, there’s sufficient reason backing the fact that IoT has the potential for more. Here’s an insight into the radical concept of the Internet of Things.

What is IoT?

The “things” in “Internet of Things” refers to both humans and every physical device with the ability to connect to the internet. The Internet of Things (IoT), therefore, refers to a network of physical devices connected to the Internet; collecting and sharing data through the use of sensors and application programming interfaces (APIs).

The emergence of cheap processors and wireless networks has created a kind of scene whereby just any device can be connected to the internet and/or to each other.

What Underlies Internet of Things?

For full and proper function, IoT relies on the hardware, the gateway, the cloud, and mobile applications or software. IoT also leverages Big Data management tools, AI and machine learning, predictive analytics, and Radio Frequency Identification (RFID) technology to work.

Today, the hype and demand for the Internet of Things (IoT) is on the rise and is expected to remain so as seen in the graph below.

Top Three Applications of IoT

It is not new to see companies announcing landmark achievements pertaining to IoT. Here are some of the useful present-day applications of IoT.

Smart Homes

Smart homes are increasingly becoming ubiquitous today. These smart home devices make our lives a lot easier and more comfortable. Imagine being able to turn on the air conditioning before reaching your house so that once you get in, it’s all cool and cozy. Well, smart home devices facilitate things like this and so much more.

Smart Homes

Some of these smart home devices include hubs and controllers, surveillance cameras, smart windows,  smart curtains, locks, and home security systems, heating and cooling devices, lighting devices, cooking gadgets, cleaning devices, health and fitness products, outdoor gear, amongst many others.


Basically, the idea behind IoT and wearables is that software and sensors are installed into everyday wearables like watches and the sensors in them collect and process data. This is in a bid to achieve a specific purpose. These include smartwatches, rings, attachments, wraps and so much more.


Smart Cities

Remember when the idea of smart cities was a futuristic thing made up of just hopes and ideas? Well, welcome to the future. The concept has morphed from dream to reality and we are catching up fast on it.

Smart Cities

By 2020, the McKinsey research projects that there will be at least 600 smart cities worldwide, and by 2025, each of these smart cities would be generating 60% of the world’s GDP. Some of these technologies include smart energy, smart transportation, smart data, smart infrastructure, smart mobility, etc.


With various applications like smart homes, wearables, smart cities, smart grids, connected cars, smart healthcare devices, smart supply chain, etc., the Internet of Things (IoT) is fast encroaching the global market and ultimately changing our lives.
