RIFD technologies are applied in a various number of environmental monitoring applications. Efficient energy management is one of the most important prerequisites for the realization of such systems and the power consumption of the RFID tag during radio transmissions must be kept low. The proposed system is composed by the RFID tags distributed on the(More)
RFID tags are used for different purposes. One of the major problems to be addressed, particularly for monitoring purposes, is their limited power autonomy. Tags must perform different tasks with limited power consumption and their batteries capacities are often too low, even if low power consumption techniques are implemented. In these operational(More)
The monitoring of power consumption has become of a great interest in recent years as well as the innovative technologies available to realize Wireless Sensor Networks (WSNs) have experienced a great growth. While smart metering technologies for electric energy are already established, as sensors power supply comes directly from power lines, WSN nodes for(More)
Wireless Sensor Networks (WSNs) have attracted an increasing attention in recent years because of the large number of potential applications. They are used for collecting, storing and sharing data, for monitoring applications, surveillance purposes and much more. On the other hand GNSSs are used in various systems devoted to monitor different atmospheric(More)
Quantitative precipitation estimation and rainfall monitoring based on meteorological data, potentially provides continuous, high-resolution and large-coverage data, are of high practical use: Think of hydrogeological risk management, hydroelectric power, road and tourism. Both conventional long-range radars and rain-gauges suffer from measurement errors(More)
During the past years, the Remote Sensing Group of Polytechnic of Turin developed a prototype of a X-band mini weather radar, capable to detect and measure rain with good space and time resolution. These radar systems may suffer for some degradations due to external factors like temperature fluctuations: some adjustment should be automatically implemented(More)
The X-band radar installed in Turin was used to analyze extreme events. About 3 years of radar maps have been analyzed in comparisons with about 30 years of measurements made by rain gauges located in the same area. The entire monitored area was divided into 4 subareas considering the complex orography near Turin, namely the flatlands, mountains, hills and(More)
The problem that we have addressed with the presented study is the absolute localization of buried RFID tags in an outdoor environment where the tag is. This is the scenario that we have envisaged when the RFID sensors are installed inside a moving body like a glacier or a slow landslide. During the tags dislocation it is possible to measure the depth of(More)
