The main characteristic of the Internet of Things (IoT) is its ability to interconnect devices through internet connectivity, enabling them to share data and communicate without human intervention. IoT encompasses a vast range of devices, from household appliances like smart thermostats to industrial sensors. This interconnectedness facilitates automation, enhances operational efficiencies, and provides real-time monitoring and analytics. The growing IoT ecosystem is transforming industries by enabling smarter urban planning, efficient resource management, and improved user experiences.
