NAME OF THE INSTRUMENT

IoT Indoor Environmental Monitoring system

 

GENERAL DESCRIPTION

Indoor microclimate monitoring system consisting of units for data acquisition and transmission (GSM or Wi-Fi), transducers of air temperature (Pt100 resistance thermometer), relative humidity (thin film capacitor with dielectric in polymeric material) and air speed and direction (ultrasound). The data collected through this monitoring system can be used to inform simulation models for the evaluation of the energy and environmental performance of buildings as well as for the model calibration and validation. The analysis with this system also allows to characterize the microclimatic conditions inside the building and their adequacy in relation to the conservation needs of the materials that make up the cultural collections and/or the building. The system allows 12 simultaneous measurements with remote data reading and control.
