Welcome everyone! Today, weβll start by defining what the Internet of Things is. Can anyone tell me what they think it means?
Is it just about smart devices connected to the internet?
Exactly! The Internet of Things, or IoT, refers to a network of physical objects equipped with sensors and software that connect to the internet. They gather and exchange data. A good example would be a smart thermostat that adjusts the temperature in your home based on your preferences.
So, does that mean anything can be part of IoT?
Yes! Anything from refrigerators to city traffic lights can be connected. This connectivity enhances their functionality.
Remember the acronym 'IoT' stands for Internet of Things. Let's move on to how it evolved!
Evolution of IoT

Now, let's explore the evolution of IoT. It all began in the **1990s** with simple connected devices. Can anyone guess what the first connected device was?
Was it something like a smart fridge?
Close! It was actually a Coke vending machine that was connected to the internet to count inventory. In the **2000s**, Kevin Ashton coined the term 'IoT' in 1999, which launched our understanding of this technology.
What happened in the **2010s** then?
Good question! That's when cloud computing emerged, allowing more devices to connect and share data seamlessly. Today, IoT continues to grow with AI and 5G technology.
It's essential to remember the timeline: 1990s for the initial devices, 2000s for the terminology, and from 2010s onward for the tech boom.

Let's discuss the key components of an IoT system. Who can name some of these components?
Sensors and devices?
Correct! The main components are: 1) Devices with sensors and actuators, 2) Connectivity options like Wi-Fi and Bluetooth, 3) Data processing either on the cloud or locally, and 4) User interfaces such as apps or dashboards. Can someone explain why each component is important?
Devices gather data, connectivity transmits it, processing analyses it, and interfaces present it to users!
Absolutely! This interconnection is what makes IoT effective and transformative.

β Define the Internet of Things.
Detailed Explanation
In this objective, you are expected to understand and articulate what the Internet of Things (IoT) is. It refers to a network of interconnected devices that can communicate with each other and with the internet. These devices collect and exchange data to improve efficiency and automate tasks.
Examples & Analogies
Think of IoT as a team of workers in an office. Each worker has different tasks (like sensors and devices in IoT), and when they communicate with each other, they create a more efficient workflow (similar to how devices in IoT share information).
