Building a Digital Twin Example – Part 2

Integrating with a Simple Telemetry Feed

The first demonstration of my preliminary ‘residential property system status digital twin’ is now complete. It’s not yet a full digital twin – it’s missing command and control functionality and is not processing all environmental data (yet) – only partial.

Residential property environmental data virtualization – a preliminary digital twin

What you’re seeing is live environmental data from a real residential space partially rendered in a virtual environment.

As mentioned, it does not represent a complete Digital Twin; however, it does show the three core components that typically comprise a Digital Twin:
(a) telemetry generation (from a physical sensor source),
(b) state synchronicity (between the physical environment and virtual environment, and
(c) a spatially-relevant 3D model.

The representation shown is the baseline ‘system status’ use case from my upcoming Northeastern University course, Building Digital Twins.
