IoT devices, or Internet of Things devices, are everyday objects that connect to the internet to send and receive data. These devices can range from smart home gadgets like smart thermostats and smart lights to wearable technology like fitness trackers. By connecting to the internet, they can be controlled remotely and can communicate with each other, making our lives more convenient and efficient. The main goal of IoT devices is to improve our daily experiences by automating tasks and providing real-time information. For example, a smart refrigerator can alert you when you're running low on groceries, while a smart security camera can help you monitor your home from anywhere.
