The correct storage and protection of works of sacred art, requires the guarantee of the optimal conditions of some parameters affecting the indoor microclimate of the place in which they are located. The temperature and humidity, are two of the most important parameters of the indoor microclimate. To avoid critical issues of the preservation process, these parameters must be kept constant during the day at each point of the place. In the conservation of works of religious art, there are two conflicting requirements: the use of the works themselves, and the need to protect the objects exposed to the deterioration, due at environmental factors. This can be achieved, by creating suitable conditions for their conservation. The arts work, usually are constituted by old materials that require for proper storage conditions depending on the type of material that constitutes them. In many cases, the ideal environmental conditions for the objects are not compatible with those most appropriate for the public. In this complex scenario the ecclesiastical monitoring, and its temperature and humidity control, exists a protocol unique accepted internationally, that establishing reference limits for the various parameters, and the only recommendations are contained in the (Italian Standardization body) UNI 10829/99. The most suitable approach, widely recognized is the "preventive conservation." This can be achieved through a mixture of measures and strategies, adapted to the case, aimed at minimizing the impact of environmental factors on the exhibited artifacts, to slow down the degradation. In this paper we present the results of a study focused on the use of wireless sensors for environmental monitoring. In this scenario with the use of the thermo-hygrometric sensors, you can realize systematic and adequate conditions.
