Environmental monitoring of heritage buildings

A system for the monitoring of microclimate and air pollutant concentrations in heritage buildings has been developed and validated by means of a measurements campaign in the Villa della Regina, a Savoy residence in Torino. The in situ campaign is currently in progress in cooperation with the Soprintendenza per i Beni Storici, Artistici ed Etnoantropologici del Piemonte. The monitoring system is composed of a wireless network of smart buttons, specifically designed to satisfy the requirements for applications in the field of cultural heritage. The smart button sensors are configured to measure temperature and humidity. Some sensor prototypes equipped also with a POF sensor for the detection of Hg vapors have been developed and are being tested in laboratory.
