Project Indoor swimming pool

Remote readout technology for an automated water disinfection system with UV sensors

Together with companies from the region, IMMS has put a novel solution for water disinfection with UV radiation into operation in the Ilmenau public indoor swimming pool. The sensor technology of this system is thus no longer only evaluated stationarily, but is connected to the cloud.

Water disinfection in indoor swimming pools – UV instead of chlorine

According to the current state of the art, chlorine compounds, among other things, are used for water disinfection in indoor swimming pools. In order to reduce the chlorine content, the partners have installed a UV medium-pressure reactor for water disinfection in the swimming pool complex. An important component of this solution is the integrated UV sensor system, which permanently monitors the correct function of the UV radiation source. The sensor data is evaluated locally in a special monitoring system, which reports deviations or failures of the UV radiation source to the process control of the swimming centre.

Remote readout of sensor and system data with IMMS solution

An existing data interface on the measuring system of the UV reactor is used to record, immediately evaluate and store the sensor data and system data permanently over longer periods of time in a simple and cost-effective manner.

With the help of the compact and energy-efficient BaseBos industrial PC developed at IMMS in the SHS-Facility project, the data is transmitted to a server via an integrated mobile modem and permanently stored there.

Via a secure internet connection, the data is displayed in browsers on any end devices, such as tablets. The solution not only provides the basis for target/actual comparisons with automatic notifications in case of deviations, but also the basis for long-term analyses and predictive maintenance of plant components.

Dr. Frank Spiller assists you with SME Digital topics as well as with the research and development of application-specific automation systems for industry:

  • Retrofittable sensors for innovative diagnostics, maintenance and service concepts
  • Universal electronic platforms for Industry-4.0-compliant components
  • Open source software and AI-based data processing for industrial applications


The demonstration solution for the indoor swimming pool is a sub-project of the Mittelstand 4.0 project. The fundamental work of IMMS on the BASe-Box platform modified for the demonstrator was funded in the project ”Modular scalable embedded HW/SW platform for energy and cost-optimised communication and data processing“ with funds from the Land of Thuringia and the European Union ( ERDF) under the reference 2010 FE 9073.

The ”Mittelstand 4.0-Kompetenzzentrum Ilmenau“ (centre of excellence in Ilmenau serving SMEs) was part of the funding initiative ”SME 4.0 – Digital Production and Work Processes“ which was funded by the German Federal Ministry of Economic Affairs and Energy (BMWi) within the funding programme ”Digitising SMEs – Strategies towards digital Transformation of Business Processes“. IMMS was funded under the reference 01MF16005C.

The work of IMMS as ”Smart Sensor Systems Model Factory“ is funded by the German Federal Ministry for Economic Affairs and Climate Action (BMWK) in the ”SME Digital Centre Ilmenau“ under the reference 01MF21008C and continues the activities from the ”Mittelstand 4.0-Kompetenzzentrum Ilmenau“.
