Air quality in classrooms
When we think about a suitable learning environment, we usually talk about teachers, methodologies, technology, and educational resources. However, there is a fundamental factor that often goes unnoticed: the quality of the air that students and teachers breathe for hours each day.
A classroom with insufficient ventilation can quickly accumulate carbon dioxide (CO₂), particulate matter, and other pollutants generated simply by the occupancy of the space. Although these pollutants are not always noticeable, their effects can be:
✔️ Decreased ability to concentrate. ✔️ Increased feelings of fatigue and drowsiness. ✔️ Reduced cognitive performance. ✔️ Increased risk of respiratory illness transmission. ✔️ General discomfort and decreased environmental comfort.
If we don't measure it, we can't improve it.
Continuous monitoring using sensors allows for real-time tracking of key parameters such as:
- CO₂
- Temperature
- Relative humidity
- PM2.5 and PM10 particles
- Volatile organic compounds (VOCs)
Having this data provides a fundamental advantage: making evidence-based decisions. This includes opening windows when necessary, optimizing ventilation systems, detecting incidents, and evaluating the effectiveness of implemented measures.
Furthermore, monitoring not only contributes to the health and well-being of students and teachers but also makes educational centres more sustainable and energy-efficient spaces.
Accurate and reliable measurements
At Morgui, we understand the importance of indoor air quality monitoring, which is why we rely on Produal, a leading European manufacturer of highly reliable sensors. From their extensive range of transmitters and environmental controllers, the RTX transmitter stands out. It measures temperature, humidity, CO₂, and VOCs. Furthermore, its temperature measurement offers an accuracy of +/-0.3°C, the highest in the HVAC market. This allows you to monitor air quality parameters and manage temperature control efficiently.
Because to learn well, you first have to breathe well.
In an increasingly data-driven society, it's paradoxical that we still don't know the air quality in many of the spaces where our children spend a significant part of their day.
And you, do you know the air quality at your children's school or your workplace? Most people don't. Perhaps it's time to start measuring it.
