Abstract
The use of a Wireless Sensor Network (WSN) has increased in the last years in many different fields. One of the main advantages of WSNs is the fast data acquisition thanks to the data gathering systems that can archive, process and send the collected data through Internet or store them in different formats. These data archiving and processing is very useful for water quality monitoring. The monitoring of water exchange in estuaries is very useful and important because it lets the researchers know and understand the changes in fauna and flora of these areas. For this reason, in this paper, we present the design and deployment of a smart system for data gathering in estuaries using WSNs. The system is based on a server which is able to request and collect data from several nodes and store them in a data base (DB). This information can be post-processed to make decisions. We also present a new conductivity sensor which is combined with our server to be used in estuaries for measure the outflow plume in estuaries. The system was tested using a FlyPort module.
