Abstract
<p class="0abstract">This paper reports the development and integration of a wireless sensor network for environmental monitoring. The main goals of this system include modularity, low power consumption and ease of expansion. The system includes three main elements: sensor nodes, gateways and a server. Each sensor node can only connect to a gateway, resulting in a star network layout. Data collected from the different sensor nodes is stored in a database within the server. A web-based user interface for this system was developed and made available online.</p>
Highlights
There has been an increase in the variety of usages for sensor systems, from industrial control and environmental monitoring to agriculture and medicine
Smart sensors are usually integrated in wireless sensor networks (WSN), based on the combination of multiple sensors in different locations with wireless communication infrastructure and software data processing
The developed system can be customized to integrate custom-built sensors for different purposes, being a building platform for the development of other remote monitoring solutions [17]. These systems may be used for various teaching activities in distinct areas, such as instrumentation for measurement, control, mechatronics, civil engineering and thermodynamics fields
Summary
There has been an increase in the variety of usages for sensor systems, from industrial control and environmental monitoring to agriculture and medicine. Smart sensors are usually integrated in wireless sensor networks (WSN), based on the combination of multiple sensors in different locations with wireless communication infrastructure and software data processing. In this way, the system can monitor and record the evolution of several parameters. The developed system can be customized to integrate custom-built sensors for different purposes, being a building platform for the development of other remote monitoring solutions [17] These systems may be used for various teaching activities in distinct areas, such as instrumentation for measurement, control, mechatronics, civil engineering and thermodynamics fields. They enable the study of the variations that environmental parameters experience depending on external conditions, allowing, for example, the evaluation of buildings’ conditions, highlighting the influence of the building materials, design approaches and predicting seasonal or periodic disturbances
