Implementación de una red inalámbrica de sensores inteligentes, con nodos robotizados para la supervisión en línea del ecosistema y contaminación del agua presente en lagos y lagunas.

Abstract

A wireless network of intelligent sensors with robotic nodes was applied for online supervision of the ecosystem and contamination of water present in lakes and lagoons using development cards. It is modular, setting up, cheap, easy installation and management system. It is structured as a unidirectional type star network, which allows the incorporation of new modules and the identification of critical areas. The designed system is able to measure variables with absolute maximum errors in water temperature ± 0,5 ° C; pH ± 0,1; turbidity ± 1 UNT; conductivity ± 1 S/cm; atmosphere temperature ± 0,5 ° C; atmosphere relative humidity ± 3% RH based on the tests applied, which measurements with an accuracy according to the intelligent sensors used in laboratories. Each measurement is accompanied by the location of the shot through the Global Positioning System (GPS) and the capture of video-images of the aquatic ecosystem. Its size and complexity is due to the dimensions of the environment. It consists of three modules that communicate for radiofrequency until 10 km without obstacles with a power supply of 5 V, WiFi and GSM. The

first called Aquatic Robotic Node formed by the monitoring sensors of the ecosystem and water pollution contained in the robotic node that navigates the lake or lagoon obtaining the data that is sent to the remaining modules. The second a Remote Ground Station that translates, visualizes, stores the information, and manage the aquatic robotic node. The third is a warning module responsible for receiving a message on the mobile device when a parameter exceeds the permissible limits, while controlling the movements of the robotic camera. The information that can be gathered with the system generates a historical databases that will allow the development of operational models to predict behaviors that affect the lakes and lagoons.
