Abstract
Health and safety issues of indoor occupants in enclosed spaces are crucial for building management. For that strict control of CO2 levels may prevent sick building syndrome, whose effects start being effective beyond 1000 ppm [1]. We developed an innovative chemoresistive material highly sensitive to CO2 over wide range despite its poor reactivity. The sensor was instrumented in a wireless, noninvasive, and portable platform for continuous monitoring. As an example, we successfully monitored CO2 concentration in an academic room for several months through data analysis by random forest and curve fitting algorithms.File in questo prodotto:
