A cost-effective solution for remote Carbon Dioxide indoor monitoring, authors: Gaudentiu Varzaru, Adrian Zarnescu, Razvan Ungurelu, Andra Gabriela Iordache

As the forth atmospheric gas in order of concentration, CO 2 is proven to affect health and productivity, thus monitoring its presence in offices, schools and industrial buildings has become a good practice The present work was generated by a real estate company request for designing and manufacturing of an in door CO 2 monitoring system The system consists in a wireless sensor network ( whose nodes are connected in a star configuration The work describes the applied research for the design of a cost effective CO 2 remote monitoring system for indoor use in office buildings which are supposed to have more than 100 rooms, based on the analysis of CO 2 sensors solutions already existing on the market Experiments with the system were performed in the laboratory and at a site at several kilometres distance.
