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...
Sensors are typically designed to produce outputs related to the instantaneous value of the quantity of interest; however situations exist where an output related to the total, cumulative or 'integral' exposure to the quantity of interest is required. This paper describes a low-cost optical sensor for the monitoring of the total exposure to sulphide vapors exploiting a non-reversible chemical reaction...
In this paper the realization and characterization of a new plastic optical fiber sensor for the detection of H2S and other sulfide compounds is described. The sensor is specifically tailored for applications in cultural heritage preservation, where the capability to evaluate the total exposure even to small quantities of pollutants is required. The substitution of plastic for glass optical fibers...
