The subject of the invention is universal network of sensors adapted to measure the concentration of particulate matter in the atmospheric air. Dust concentrations which are suspended in the air is monitored in three mass categories:

PM1 - particles with a size of 1 micrometer or smaller

PM2.5 - particles with a size of 2.5 micrometers or smaller

PM10 - particles of 10 micrometers or smaller,

and number of particles per volume unit in 6 categories of pollen diameters: > 0.3 μm,> 0.5 μm,> 1.0 μm,> 2.5 μm,> 5.0 μm,> 10.0 μm

The system also allows to measure temperature, humidity and pressure. The measurement results can be observed on-line on the website: What is important, in comparison to similar solutions existing on the market, the sensors can be regularly calibrated, which makes the results much more reliable.

The advantages of technology are the following:

- low cost of use;

- very quick start of field measurement;

- maintenance-free work of the station;

- access to on-line measurement results;

- sampling data with a resolution of 1 minute;

- auto-location (have GPS receivers);

- time synchronization (three sources: stable RTC clock, internet network, GPS signal);

- power supply or battery (6V <Vdc <36V);

- stations can work stationary or on a mobile platform (buses);

- we have a calibration system that enables periodic calibration of sensors.

Further development of the invention is performed at the Department of Experimental Computer Physics, Faculty of Physics, Astronomy and Applied Computer Science of the Jagiellonian University. Centre for Technology CITTRU is looking for entities interested in licensing and application of the technology described above.

JU scientists to develop biological agricultural support solutions
The project “Interactions between plants and microorganisms in response to the presence of potentially toxic metals, metalloids and silicon (Si)” by Prof. Katarzyna Turnau from the JU Faculty of Biology won a grant from the Polish National Agency for Academic Exchange. The study aimed at replacing the widespread use of agrochemicals with biological agricultural support solutions will also involve researchers from Slovakia and Austria.
JU students will help people suffering from depression
Therapify is a mobile application designed to help depressed people. It was first conceived by Łukasz Pstrong, a graduate of the AGH University of Science and Technology in Kraków, and developed over the course of the last two years with collaborators from his university, the Jagiellonian University, and SWPS University of Social Sciences and Humanities in Warsaw.
Plakaty Demo Day II +
In January, we complete the project managed by CTT CITTRU as part of the program of the Ministry of Science and Higher Education - Incubator of Innovation +. We supported, among others, 18 research teams selected in the competition, that develop innovative technologies. Thanks to the funds granted by CTT CITTRU and hard work of technology transfer officers, pre-implementation research was financed, which increased the attractiveness of these inventions and investors interest in them. Take look at the gallery of posters for technologies, developed as part of the project. What do you think about it
