Measuring the quality of the indoor environment using IoT sensors developed in the laboratories of the University Center for Energy Efficient Buildings of the Czech Technical University has started in several schools in the Prague 7 district. This is a pilot phase of the introduction of a new technology that its creators offer for licensing to potential manufacturers.
IAQ 03 sensors are deployed at a total of fourteen measuring points in one kindergarten and two primary schools in Prague's Holešovice, which continuously monitor the concentration of carbon dioxide and volatile organic substances, relative humidity, temperature and barometric pressure. A new feature of this sensor model is the dust level measurement function. The sensors send the acquired data to cloud storage and can communicate via WiFi and bezdrátovou síť LoRaWAN.
"The results will make it possible to assess the effect of greenery on dust in buildings and to compare the concentration of carbon dioxide in rooms depending on their operation. Thanks to this, it will be possible to accurately evaluate the effect of different ventilation systems," says Michal Kuzmič from ČVUT UCEEB. The measurement takes place within the project Technologický transfer pro chytrou Prahu supported by the Operational Program Prague – growth pole (CZ.07.1.02/0.0/0.0/16_0403/0000364) and the budget of the capital city of Prague. It should be completed this spring.
