Diseño de un prototipo de una red de sensores inalámbricos para el monitoreo de la calidad de agua para uso recreativo en el Dique Fátima.

Abstract

The objective of the present research work was to design a prototype of wireless sensor networks to monitor water quality for recreational use in the Fatima Dam. The prototype RMF consists in a wireless network which includes sample modules, and a data collection module to perform an on-site monitoring of water quality. For on-site monitoring evaluates dissolved oxygen, temperature, pH and turbidity using sensors placed in the sample module. The sample module sends the data obtained by wireless communication to the data collection module, where stores in a flash memory and a Google Drive account. The stored data can be analyzed in the end user application, created with the software Labview 2016. On the other hand, it verified that the dissolved oxygen sensor has an absolute error of +/- 0.05mg/l, the sensor of pH +/- 0.08, the temperature and turbidity sensors have a minimum error. In addition, the repeatability test showed that the data obtained from all sensors tend to be homogeneous. The wireless communication tests showed that the communication is successful to 160 meters; being enough to cover with the distances required in the design of the network. It concludes the prototype RMF is efficient because comply with the requirements of the network, besides it obtains reliable data and its complete implementation requires 50% about the price of equipment in stock. The prototype presented consists of a single sample module and a data collection module. Finally, it recommends implementing two more sample modules to know the behavior of the river, before and after the dam.
