Implementación de una red de sensores inalámbricos LPWAN mediante módulos LoRa para el monitoreo de la calidad del agua en 2 ríos

Abstract

In this document is shown the design and the implementation of a Wireless sensors network to measure water quality parameters in rivers using low budget components. Modules LoRa™ are employed for the communication between nodes, which is a technology arised with the boom that the WSN (wireless sensors networks) have had, the IoT (Internet of things) and the M2M. The LoRa modules have great features because of their low energy consumption having in mind the big distances that they reach and their low cost, reason for which they are the adequate technology to accomplish the purposes of the project. Two modules are built to sense the following parameters: electric conductivity, pH, Temperature. Therefore the acquisition, desing and construction of the conditioning circuits is made. A receptor node is also made which will be connected to a computer and will display the data through a graphic interface programed in java
