MONITORING AND CONTROL OF HYDRAULIC SYSTEMS THROUGH FLOW SENSORS, RF COMMUNICATION, AND WEB-BASED INTERFACE

Abstract

This article presents the development of a hydraulic monitoring and control system using flow sensors, wireless RF communication (nRF24L01), and an embedded web interface. The proposed system aims to provide a low-cost and easily deployable alternative for residential or rural water-supply automation. The system consists of two nodes: Node_A, based on Arduino, reads level and flow sensors and controls a water pump; and Node_B, based on ESP32, receives data via nRF24L01 and displays real-time information through a local Webserver. Tests demonstrated reliable communication, accurate flow readings, and effective automatic control. The solution contributes to sustainable water use and can be expanded to IoT and smart-farming scenarios.
