Project Description


Siemens – Sensformer Application for Hannover fair

The app visualizes the digital twin of a transformer, which is equipped with many sensors (sensformer). Data extracted from MindSphere (Siemens Cloud Solution) is displayed. Mindsphere provides live data through a WebAPI.

The 3D model highlights various data such as dimensions, running fans, sensor placement, as well as a temperature distribution on the various coils using heat map. Individual components can be inspected more accurately in 3D (real size or miniature).

Further functions support the evaluation of the data and enable a better recommendation for action (temperature curves and utilization).


  • Processing of CAD data

  • UI and UX

  • Animations

  • Create 2D and 3D elements


  • ARKit

  • Unity 3D

  • API Connection


Visitors to the Hannover Messe were able to experience the advantages of the Sensformer compared to conventional transformers with the help of augmented reality.

In addition, Siemens has demonstrated the possibilities of linking disruptive technologies within the scope of this application.
