Diseño de un sistema inalámbrico para georreferenciar puntos de contaminación de agua potable en hogares.

Abstract

Is interesting to know the quality of the vital fluid, because an electronic system was developed, based on the analysis of physiological parameters that determine the quality of the potable water that is supplied to homes in the city of Riobamba, in order to georeferenced pollution points. The system has a physical node and a storage node, the physical node determines four physicochemical parameters: chlorine pH, temperature and turbidity, it also has a control system that allows water quality labelling of contaminated water, ensuring that water that enters the home is quality water. The storage node is represented by a web page which is essential for georeferencing, the processing of the information was done through the free hardware platform of Arduino and the transmission of data through GPRS using the FTP protocol. The reading of data is done every two seconds and the transmission of information to the web page takes one minute before the next reading, on the web page a map with the points where the water does not conform to the established standards is displayed by the competent entity. The efficiency was determined by subjecting the system to different types of contamination, exceeding the permissible limits, obtaining an average turbidity error of 0.09 NTU, temperature 0.09 degrees Celsius and chlorine of 0.09ppm, which indicates that the error is below the error itself of each sensor. It is concluded that the system implemented, has a high degree of functionality and efficiency, in a way that prevents the supply of contaminated water to households as well as providing information to be used by the control entity, since georeferencing is provided in sectors where there is contamination allowing immediate action.
