Novel Wireless Sensor System for Dynamic Characterization of Borehole Heat Exchangers
2011
The design and field test of a novel sensor system based in autonomous wireless sensors to measure the temperature of the heat transfer fluid along a borehole heat exchanger (BHE) is presented. The system, by means of two specials valves, inserts and extracts miniaturized wireless sensors inside the pipes of the borehole, which are carried by the thermal fluid. Each sensor is embedded in a small sphere of just 25 mm diameter and 8 gr weight, containing a transceiver, a microcontroller, a temperature sensor and a power supply. A wireless data processing unit transmits to the sensors the acquisition configuration before the measurements, and also downloads the temperature data measured by the…
AN INNOVATIVE SYSTEM FOR VINEYARD MANAGEMENT IN SICILY
2010
The aim of this study was to monitor the micro-climate of the grapevine in order to detect the adversities of the spring period (especially April and May), while reducing the operating costs of the vineyard, and increasing the overall quality of grapes. For this purpose a Wireless Sensor Network (WSN) was used. Furthermore, a comparison was performed between data measured by the wireless sensors and data provided by the fixed meteorological station of the Regione Siciliana (SIAS).

A novel device for assessing the health risk caused by hand-arm vibrations in olives harvesting
2012
The mechanization of olive harvesting is very important both to reduce the costs of production and to assure the oil quality because the manual harvest does not allow to operate at the right time and also need a long period to be completed. The use of portable shakers, that are spreading more than others typologies, can give a solution to the problem. However, the use of such equipment may involve risk of exposure to hand-transmitted vibration. The aim of this study was to assess the level of exposure to hand-arm vibration of the operators using portable shakers (reference standards UNI EN ISO 5349-1:2004, Italian Low Decree 81/2008). The research presented here concerns the definition of a…
A system to monitor the main ambient parameters in the vineyard with wireless sensors
2009
Wireless technologies have been under rapid development during recent years but applications of wireless sensors in agriculture and food industry are still rare. The aim of this study is to monitor the micro-climate of the grapevine in order to monitor the adversities of the spring period reducing the operating costs of the vineyard and increasing the quality of grapes. At this purpose a Wireless Sensor Network (WSN) was used. Furthermore, a comparison was performed between the data measured by the wireless sensors and the data provided by the fixed meteorological station of the Regione Siciliana (SIAS).
