A modular sensor integration system for Industry 4.0 Smart Factory

Sensor Technology Adapter Gateway - STAG is an open-source project aimed at easing sensor system integration to data visualization and management software.

Smart sensor systems are one of the central aspects of the smart factory in Industry 4.0, however, separate sensor systems from various vendors frequently use different or even proprietary communication protocols. This can cause complications when integrating all of these systems into a common communication protocol or even an Internet of Things (IoT) platform. It gets even more complicated when the same sensor systems need to be integrated into separate parallel IoT platforms or databases to support different use cases. For example, an IoT platform to monitor real-time state of various sensor systems and a separate database, optimized to store statistical data from the sensor systems for a predictive maintenance system.

Our modular gateway reduces the integration complexity by abstracting various different sensor communication technologies and protocols with a unified information model combined with an automated data mapping. Furthermore, STAG can be easily scaled by adding new sensor adapters without having to manually expand the IoT platform models as well as providing a simple interface for future IoT solution integrations.

An award winning solution

Factory Innovation Award 2025

The “Factory Innovation Award” is one of Europe’s most prestigious awards for smart factory software. An independent jury of distinguished digital and industry experts—including journalists, consultants, users, and researchers selects a winner in each category. Finalists present their solutions in a digital pitch, and the winners are announced and celebrated at an award ceremony during Hannover Messe. The award is organized by the Center for Industry 4.0 at the University of Potsdam, in partnership with the Berlin-based GITO publishing house and the FACTORY INNOVATION trade journal, the leading publication for the Smart Factory market.

STAG software was awarded the Factory Innovation Award 2025 for research institutions in the connectivity category on the Digital Transformation Stage at the Hannover Messe in 2025.04.03
