Learning Objectives
By the end of this chapter, you will be able to:
- Define the Internet of Things (IoT).
- Describe how an IoT system works.
- Provide examples of IoT applications.
What is the Internet of Things (IoT)?
The Internet of Things (IoT) refers to the network of physical objects—“things”—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet.
How IoT Works
- Sensors collect data from the physical world.
- Connectivity sends that data to the internet.
- Processing of the data happens in the cloud.
- An Action is triggered or information is presented to a user.
Examples of IoT
- Smart Home: Smart thermostats, lighting, and security systems.
- Wearables: Smartwatches and fitness trackers that monitor your health.
- Smart Cities: Connected traffic lights, smart parking meters, and waste management systems.
Summary
The Internet of Things is a giant network of connected devices that collect and share data about the world around us. From our homes to our cities, IoT is making our environments smarter and more responsive. This trend is set to accelerate as more and more devices become connected to the internet.
Key Takeaways
- IoT is a network of connected physical objects.
- IoT systems collect, send, process, and act on data.
- Smart homes, wearables, and smart cities are all major applications of IoT.
Discussion Questions
- What is an example of an IoT device that you use in your daily life?
