Diseño e implementación de un prototipo de monitoreo de flujo de agua mediante GSM y radio frecuencia en un circuito local de agua potable.

Abstract

It was implemented an intelligent electronic system for Measurement, Control, Visualization and Fault Alerting in local circuit of low cost drinking water, easy implementation which allows the monitoring through a web page. The development of the prototype is an attempt to provide quick solution, since there are faults in the potable water distribution pipes. It generates a lack of service to user and loss of liters of the water until the solution of the same. The prototype allows adding new modules of obtaining data and control. It has two modules developed in the Arduino platform. The communication between the modules is by radio frequency using the module NRFL24L01 with a maximum distance of 40m of transition and reception. The first module called node, has an electrovalve that allows the stop or passage of water to the branch that is controlled by the system. Flow sensor YF-S201 were used to obtain the data. These data are sent in an orderly way to the second module, the information received has an identifier that facilitates the processing in order to control each node it sends an activation message or deactivation of the solenoid valves. In addition, it sends a text message through the global system for mobile communications (GSM) when there is failure in the branches. The processed data are stored in a database for a set time. From the tests performed it is verified that the device has a minimum census error that is negligible in each of the sensor. Each measurement was made in comparison to the volume water. It is concluded that the prototype allows a fast a control of the produced faults in a potable water circuit, which gives a stability of the service to the users. It is recommended to avoid error in obtaining flow data through always calibrating the sensor.
