... about a crossing over of price and functionality between sensor networking technology and communications technology. This makes possible the installation of smart sensors on remote places, transmitting the measured information to the final user (a client). A simplified block diagram of hardware implementation of a remote smart sensor is shown in Fig. 4. In the first section the physical quantity under measurement is transduced and then conditioned for the A/D converter input. The samples, acquired by the A/D converter, are pre-processed (i.e. averaging the measurements, changing the scale) by a local processor (microcontroller). A smart sensor can also include high hierarchical level ...

... changing the scale) by a local processor (microcontroller). A smart sensor can also include high hierarchical level applications, such as electronic data sheets, self-identification, self-testing, self-adaptation, smart calibration and compensation. The sensor needs to be able to communicate for remote monitoring and remote configuration; in Fig. 4 is the last block, the networking embedded system, that performs the final processing, storing and data ...

In this paper we evaluate the performance of Wisden - a wireless multi-hop sensor network based data acquisition system for structural health monitoring (SHM) applications. We deploy Wisden in two real environments: a seismic test structure and a four story office building. We examine several aspects such as reliability, latency and data integrity...
In recent years, there has been an increasing interest in the adoption of emerging sensing technologies for instrumentation within a variety of structural systems. Wire- less sensors and sensor networks are emerging as sensing paradigms that the structural engineering field has begun to consider as substitutes for traditional tethered monitoring sy...
In recent years, owing to the shortage of oil and gas resources and increased difficulty in mining, traditional (wired) microseismic monitoring equipment has been unable to meet the needs of energy exploitation. Therefore, it is necessary to develop new high-precision seismic exploration and data acquisition systems. In this study, we combined adva...
