Wireless Sensor Network for Environmental Monitoring of Cultural Heritage

Abstract

Cultural heritage assets represent the history and unique identity for every nation in the world, so their protection and conservation are mandatory tasks. However, although such assets are usually exhibited in special museum rooms, sometimes the environmental conditions may be modified, putting the materials at risk. These facts can be more severe in warehouses, where environmental conditions can vary even more. Most of the measurement sites are located in spaces that make it difficult or do not allow the handling of commercial devices for measuring multiple environmental parameters, either due to their size, energy consumption or because they cannot be connected to the internet, so there is no timely availability of information on the environmental condition in which they are found. This work presents the design and implementation of a wireless sensors network based on Bluetooth Low Energy and ZigBee, able to measure temperature, moisture, light intensity and irradiance, and particulate matter 2.5 and 10, in the different spaces where objects of cultural heritage are found. These measurements are sent to a web platform through the use of Wi-Fi or GPRS technology.
