Understand how physical objects connect to the internet, communicate via sensors, and build smart environments.
Hook and introduction to IoT.
Imagine if your smart bulb, fan, and refrigerator could talk to each other to save energy while you are away. This is the reality of the Internet of Things (IoT).
IoT is a network of everyday devices that contain embedded hardware and software. This allows them to seamlessly connect, communicate, and exchange data over a shared network.

Everyday devices connect to the cloud and communicate to form an intelligent network of things.
Defining Web of Things and smart sensors.
If you have 10 smart devices, installing 10 different apps to control them is frustrating. The Web of Things (WoT) solves this by using standardized web services to connect physical devices into one unified interface.
Sensors act as the monitoring elements of the physical world. For example, an accelerometer detects the orientation of your phone, while a gyroscope tracks the twist and rotation of your hand.

Examples of IoT applied in smart city infrastructure.
With rapid urbanization, city planners turn to IoT to manage massive infrastructural loads. In a smart city, transportation, water, and power networks work in unison to optimize operations.
Imagine a skyscraper equipped to feel the earth move. A smart building uses sensors to detect early earthquake tremors. It can instantly send alerts to warn nearby buildings, giving them critical seconds to prepare.
