Abstract
<p class="Abstract">Most sensing networks rely on punctual/local
sensors; they thus lack the ability to spatially resolve the quantity to be
monitored (e.g. a temperature or humidity profile) without relying on the
deployment of numerous inline sensors. Currently, most quasi-distributed or
distributed sensing technologies rely on the use of optical fibre systems.
However, these are generally expensive, which limits their large-scale
adoption. Recently, elongated sensing elements have been successfully used
with time-domain reflectometry (TDR) to implement diffused monitoring
solutions. The advantage of TDR is that it is a relatively low-cost
technology, with adequate measurement accuracy and the potential to be
customised to suit the specific needs of different application contexts in
the 4.0 era. Based on these considerations, this paper addresses the design,
implementation and experimental validation of a novel generation of
elongated sensing element networks, which can be permanently installed in
the systems that need to be monitored and used for obtaining the diffused
profile of the quantity to be monitored. Three applications are considered
as case studies: monitoring the irrigation process in agriculture, leak
detection in underground pipes and the monitoring of building
structures.</p>
