Smart climate chambers

IoT Solution for climate chambers


Extensive data streams from a large number of climatic and environmental simulation units must be received, stored and subsequently processed in a secure, high-performance and scalable manner. Ultimately, the fastest possible retrieval of the data should also be ensured.


Creation of a comprehensive and scalable cloud infrastructure with Microsoft Azure. In addition, the conception and development of microservices and the safeguarding of their interplay was carried out in order to prepare and output very large quantities of measurement data.


Multiple different integrators assigned by the customer can attach their perspective software tools on the solution that has been created. A first integrator is developing a tool to successfully enable the user-friendly evaluation of measurement data for test reports.

Weiss Umwelttechnik, based in Reiskirchen-Lindenstruth, Hesse, specializes in innovative and reliable environmental simulation systems. With the test systems, various environmental influences (temperature, climate, corrosion, dust or combined stress tests) can be simulated in fast motion.

As part of a broad-based digitization initiative, Weiss Umwelttechnik has decided to expand its existing software offerings. Leading in the field of climatic simulation units and successful in the market for years with the software "Simpati", new digital products are being developed, which use the advantages of cloud-based environments to further optimize the company's market penetration. Since tresmo already had experience from previous projects with similarly high demands in terms of cloud infrastructure, the implementation of a first Minimal Sellable Product was started quickly in spring 2017, following a detailed requirements analysis.

Together with an integrator assigned by Weiss Umwelttechnik, who took over responsibility for the front-end of the application, the tresmo engineering team focused on a robust and flexible microservice architecture to provide the required data in the back-end. In addition to the aspects of data preparation, data security (authentication, authorization, user/role concept) and multi-client environment, the integration of the decentralized air conditioning units into the cloud (connectivity) was assigned central importance. In close cooperation with a team at Weiss Umwelttechnik specialized in the devices, a solution was developed to enable all Simpati operated devices to send measurement data into the cloud. Parallel to the ever-growing microservice landscape, the tresmo team created an individually tailored infrastructure in view of the enormous data volume. On the one hand, this infrastructure is scalable in the long term and on the other hand, it remains easy to maintain due to the high degree of automation. In the sense of a long-lasting, constantly evolving product, the manageability of this sophisticated overall architecture was a core objective of tresmo.
