🌐 Internet of Things (IoT) & Smart Homes
What is IoT?
The Internet of Things (IoT) refers to the network of physical devices (“things”) embedded with sensors, software, and connectivity, enabling them to collect and exchange data over the internet.
What are Smart Homes?
Smart Homes use IoT devices to automate and remotely control household functions — like lighting, heating, security, appliances, and entertainment — often through smartphone apps or voice assistants.
🏠 Key Components of Smart Homes IoT
