Testing the project with Prague students

The trial operation will take place at the Smíchov Secondary Industrial School (SSPŠ), which is ideal for testing in the demanding conditions of urban development and heavy road traffic due to its structure and location. Another advantage is that it is a technically oriented school that wants to use the measurement results in vocational training.

“With the Healthy School project, we would like to open a discussion on the topic of quality living conditions in cities and its impact on our health. We believe that the use of innovative technologies can significantly contribute to its improvement,” says Václav Provazník, managing director of O2 IT Services.

“From our participation in the project, we expect not only an improvement in the quality of the indoor environment for our students and school staff, but we also greatly welcome the opportunity for students to engage in measurements and experiments. The practical experience with new technologies that students can gain thanks to O2 ITS is invaluable,” says Radko Sáblík, director of SSPŠ.

How it works

The subject of the pilot project is long-term measurements of the indoor environment in selected classrooms and the external environment outside the school towards the street and into the inner courtyard. Sensors are installed in ten classrooms that continuously measure the levels of indoor air pollution through the concentration of carbon dioxide (CO₂) in the air, relative humidity, and temperature. At the same time, two sensors are placed in the school to measure the level of pollution in the external environment through dust particles.

Last but not least, noise levels are also measured at several locations in front of the school windows. During the pilot project, a series of experiments will be conducted to verify the impact of the testing measures on changes in the indoor environment at the school.

The individual sensors transmit real-time data (temperature, CO₂ levels, humidity, etc.) to the internal system of O2 ITS 24 hours a day, allowing the climate in the classrooms to be monitored at any time. At the same time, selected students record specific data about events in the classroom, such as time or the number of students. Thanks to this data, it will be possible to analyze the measurement results in detail and provide specific recommendations.

Project benefits

After the pilot operation, O2 IT Services, together with the project partners, will conduct an analysis that will describe the relationship between the levels of pollution in the indoor and outdoor environments and specific situations in the school. The analysis will also include proposals for individual steps that would allow the school to manage the situation in the area of the environment during the presence of students and teachers in the school building. Another benefit will be the verification of technology and the determination of the necessary range of components for smart environmental management in buildings.

PROTRONIX s.r.o. – provided space sensors for monitoring air quality indoors. The sensor measures the concentration of carbon dioxide (CO₂) in the range of up to 5000 ppm, temperature, and relative humidity.

CAMEA, spol. s r.o. – installed two devices on the school building facing the street and the courtyard for fully automatic informative monitoring of outdoor air pollution; the sensors measure dust particles and the concentration of carbon monoxide (CO) in the air, alongside basic parameters such as temperature, humidity, and air pressure.

IQRF Alliance s.r.o. – connected individual industrial partners and academic institutions using the IQRF communication platform. The companies O2, Protronix, and MICRORISC are members of the IQRF Alliance.

MICRORISC s.r.o. – provided IQRF transceivers creating a transmission system that ensures wireless transmission of sensor data.

Environmental Protection, s.r.o. – conducts accredited measurements and, as part of the pilot project, provided a noise sensor that will continuously measure and record the equivalent level of acoustic pressure at various locations in front of the school windows.
