A device known for its ability to connect to the internet and collect data is called an IoT device, or Internet of Things device. These devices, such as smart sensors, smart thermostats, and wearables, enable real-time data collection and communication. They play a crucial role in fields like smart homes, healthcare, and industrial automation. By leveraging connectivity, IoT devices help improve efficiencies, provide valuable insights, and enhance user experiences, ultimately contributing to the growth of the smart ecosystem.
