The Internet of Things (IoT) refers to the network of interconnected physical devices or “things” that communicate and exchange data with each other through the internet. These devices are embedded with sensors, actuators, and other technologies, allowing them to collect and share information. The goal of IoT is to create a smart, interconnected ecosystem that enhances efficiency, automation, and data-driven decision-making.

How do IoT Devices work?

Equipped with sensors and actuators, IoT devices collect and process data, enabling functionalities such as temperature sensing and motion detection. Data analysis occurs locally or in the cloud, providing valuable insights and triggering actions autonomously. Automation is a key feature, exemplified in smart home devices adjusting settings based on occupancy. Interoperability standards ensure seamless communication among devices from different manufacturers.

Examples of common IoT devices

IoT devices span a wide range of industries and applications, enhancing connectivity, automation, and data collection. Here are some examples of IoT devices:
