MeteoSchweiz measuring pollen levels using Swisens technology


Horw LU – The 20 percent of the Swiss population that suffer from hay fever will know precisely what kinds of pollen are contained in the air around them from the next pollen season onwards. Using technology developed by the Horw-based Swisens AG, the measuring stations located right across Switzerland will deliver data in real time for the first time.


The Swiss pollen measuring network is to be automated, according to a press release. At the moment, MeteoSchweiz is in the process of equipping its measuring stations across Switzerland with a new technology developed by Swisens AG. The Swisens Poleno system is able to automatically determine the type and concentration of pollen in real time. The first stations will be ready in time for the 2021 pollen season, with the network as a whole is scheduled to be operational from 2022 onwards.


Up to now, a manual method for measuring pollen has been the international standard. The drum in the measuring stations is sent to the laboratory once a week. This is where the tricky task of identifying the pollen types under the microscope takes places. For this reason, the pollen concentrations published on a Wednesday, for example, actually reflect the levels seen in the previous week


Using the high-tech aerosol particle measuring system from the Horw-based Swisens AG, this process will take just a matter of minutes. It is based on holography and Artificial Intelligence (AI). According to information from Swisens, this allows a “particle classification and long-term monitoring of particles in the ambient air to a degree never seen before”.


Detection is also not limited solely to pollen. The Swisens website explains: “We are working on an extension for additional particles, such as mold spores and excrement from dust mites”.


Swisens AG is a start-up with specialists in aerosol technology, high-tech engineering, big data and AI. It was founded in 2016 as a spin-off from the Lucerne University of Applied Sciences and Arts.
