Air quality measuring at school
06 March 2019
Wireless sensors for measuring CO2 concentration, temperature, relative humidity and atmospheric pressure were installed in 40 classrooms and laboratories. Two IoT Starter Kits with the same wireless sensor were delivered as a part of the installation. The entire project, including technical support and data visualization, was delivered by the Department of Cybernetics and Biomedical Engineering, FEI, VŠB - TU Ostrava. The project was implemented with the financial support of the Moravian-Silesian Region within the "Smart region" strategy.
The air quality monitoring system is based on the IQRF wireless technology platform from the Czech company Microrisc, s.r.o.. The complex solution was developed by the team consisting of Ing. Jan Velička, Ing. Martin Pieš, Ph.D., Ing. Radovan Hajovsky, Ph.D. and Ing. Richard Velička, Ph.D. from the Department of Cybernetics and Biomedical Engineering. The basis of the system is a wireless measuring sensor that measures CO2 concentration, temperature, relative humidity and atmospheric pressure.
All measured data is archived in a database and visualization is performed through the Grafana software system. Access to data visualization is enabled through the web interface.
The aim of the project is to evaluate the air quality in the educational premises of the school on a long-term basis, which has a significant influence on pupils' focus. Based on the data being evaluated, measures can be taken in the form of frequent and intensive ventilation.
