Design of a monitoring, alert and control system for indoor exhibition spaces

The environmental parameters (temperature, relative humidity, UV factor, light intensity and others) of an indoor exhibition space must be monitored and controlled in order to ensure proper conditions for artifacts' preservation. This can be done by a monitoring, alert and control system (MACS) consisting of a sensor network, a communication infrastructure and a central processing device. Data are measured and collected by sensors, sent by the communication network and, finally, stored and processed into the central node (NC). Based on the analysis of data, decisions are made, alerts are sent to the responsible personnel, by short messages to the mobile phone or by email, and commands are sent to the actuators in order to turn on the environmental control devices (air conditioners, heating or light control devices and others). The goal of MACS is to provide efficiently and economically a stable quality of the indoor exhibition environment. A case study is done for an exhibition room from the Metropolitan Museum of Iasi.
