The **Internet of Things** (IoT) refers to the network of physical devices embedded with sensors, software, and connectivity that collect, exchange, and act on data—from smart thermostats and wearable health monitors to industrial sensors and autonomous vehicles.

The IoT ecosystem has grown to over 18 billion connected devices worldwide, projected to exceed 30 billion by 2030. The proliferation of low-power wide-area networks (LPWAN), [5G](https://metavert.io/glossary-5g) connectivity, and [edge computing](https://metavert.io/edge-computing) has solved many of the connectivity and power constraints that limited early IoT adoption. Matter, the unified smart home protocol backed by Apple, Google, Amazon, and Samsung, has brought interoperability to consumer IoT after years of fragmentation.

Industrial IoT (IIoT) represents the highest-value segment. Factories, energy grids, supply chains, and infrastructure systems use IoT sensors to monitor conditions, predict failures, and optimize operations in real time. When combined with [digital twins](https://metavert.io/digital-twin), IoT data creates a continuously updated virtual model of physical systems. Predictive maintenance alone saves industries billions annually by identifying equipment issues before they cause downtime.

[AI](https://metavert.io/artificial-intelligence) has transformed IoT from data collection to autonomous action. Edge AI processes sensor data locally, enabling real-time decisions without cloud round-trips. [AI agents](https://metavert.io/agentic-ai) can monitor IoT networks, identify anomalies, coordinate responses, and optimize system performance autonomously. The convergence of IoT, AI, and [distributed networks](https://metavert.io/distributed-network) is creating an ambient intelligence layer across physical environments—where the built world becomes responsive, adaptive, and increasingly self-managing.
