Diseño e implementación de un prototipo IoT para monitorear las características físicas del agua de consumo humano en los tanques de Huillis y Guanando.

Abstract

The water collection system located in Huillis and the distribution system in Guanando lack oversight and assessment of the physical attributes of water for human consumption. Consequently, tank cleaning is initiated exclusively upon the detection of water turbidity. Therefore, the objective of this technical project was to design and implement an IoT prototype to monitor the physical characteristics of water for human consumption in the tanks of Huillis and Guanando. The technical project follows the following sequence: analyzing the implementation site with coverage tests using LoRa modules RYLR998 and RYLR993, prototype construction, and calibration of sensors to be placed in the water tanks. The data collected by the sensors are sent from slave nodes to master nodes of each system, where the master node publishes the sensed data to the broker using WiFi technology and the MQTT communication protocol. Then, data is retrieved from the broker via subscription using Node-RED on a server to analyze, process, and store the information, visualized through a dashboard. Through this process, it was feasible to monitor the physical attributes of water, encompassing Total Dissolved Solids (TDS), pH levels, and turbidity, employing various sampling intervals and acquiring reports for an 8-day assessment of sensing, thereby confirming the effectiveness and operability of the prototype. In this context, it concluded that the prototype functions and facilitates real-time and remote monitoring of the physical characteristics of water contained in the tanks, allowing for preventive actions to provide better quality water for human consumption.
