Smart Sensor System for Remote Monitoring of Grains Stored in Plastic Bags (Silo Bags)

This paper presents a smart sensor system capable of continuously and unsupervisedly monitoring the quality and condition of grains stored in silo bags located in remote locations. The system mainly comprises multiple sensing units, which can measure relevant physical and chemical parameters used to assess the grain moisture, the biological activity inside the silo bag and to detect a potential theft or vandalism. A prototype of the system was fabricated and experimental results obtained during field tests are reported.
