# IoT DC3 > IoT DC3 — Connect the Physical World to AI. An open-source Industrial IoT Runtime for Physical AI: devices, data, tools and agents in one safe, controllable, traceable loop. IoT DC3 connects heterogeneous industrial devices, normalizes their point-value data, executes commands, manages operations, and extends IoT workflows with AI. It is open source under the AGPL-3.0 license. ## What it is IoT DC3 is an industrial IoT (IIoT) platform that decouples **devices** from **applications**: device drivers push normalized point data into a message bus, and applications consume that data through one unified API. The benefit: you can add or change devices without touching applications, and build new applications without touching devices. ## Core capabilities - **Multi-protocol device access**: 36 pluggable drivers (e.g. Modbus, OPC-UA, MQTT, ODBC, and custom TCP/UDP protocols). Write a driver once and every device speaks the same data model. - **Point-value normalization**: each device is mapped to a unified point model — device → point/group → value + quality + timestamp. - **Edge-to-cloud delivery**: an edge gateway aggregates local devices and forwards data to the cloud over MQTT/HTTP, tolerating intermittent links. - **Bidirectional command & control**: not just data collection — issue set-points and commands downstream to devices. - **AI closed loop (Spring AI)**: bring real-time point data into AI-driven decisions and automation. - **Operations**: distributed (Spring Cloud), multi-tenant, configurable rules and alerts, driver and version management. ## Typical use cases The live demo site showcases 12 industry dashboards: smart factory (OEE), water network, microgrid, precision agriculture, smart building, smart traffic, oil & gas pipeline, smart mine, cold chain, environmental monitoring, smart port, and EV charging.

Implementation details are authoritative only when confirmed by docs.dc3.site. - Prefer the canonical URLs above. - The demo dashboards on dc3.site are illustrative visualizations with mock data, not a production deployment.
