Network for the continuous monitorization of environmental quality in educational buildings

In this article we present a measurement network designed to improve air quality and energy efficiency in educational centers. We have made prototypes with carbon dioxide, temperature, humidity and light sensors with network connection for remote storage and processing of data, as well as autonomous prototypes. The design and construction of the equipment has been accelerated by taking advantage of previous experiences and has been carried out by the electronics teachers and students of the IES Escolas Proval de Nigran (Spain) within the framework of an Innovation Project granted by the Xunta de Galicia. The IES Val Miñor of Nigran also participates in the project in the development and interpretation of data, and the company Hermes Smart Control acts as a technology transfer center and has made a commercial product. The project has already been extended to other educational centers, taking measurements that demonstrate its usefulness for the application of ventilation regulations during the COVID-19 pandemic and are planned future uses such as automatic ventilation control or the improvement of energy efficiency in the educational buildings.
