Proposta de um sistema microcontrolado simples e de baixo custo para o monitoramento do consumo doméstico da água - fase de prototipagem

Abstract

This study presents a proposal for a simple and low-cost microcontrolled system aimed at monitoring water consumption in residential environments. Initially, the contexts and reasons leading to occurrences of illegal connections are explored, detailing their implications through a literature review. The study included a thorough survey of the necessary components, obtained through market research and selection criteria based on cost analysis. Subsequently, a detailed design of the prototype for monitoring water consumption was conducted, using modeling and simulation software to ensure its efficiency. Additionally, a channel was set up on ThingSpeak, for mobile or desktop application, as a testing method to ensure data integrity and report generation. The study also involved simulations to evaluate the performance of the proposed system, employing specific software (ThingSpeak) for testing in different consumption scenarios, followed by a comparative analysis of the results obtained. The conclusions highlighted the constitution of the prototype as the central element of the system, emphasizing its efficiency in data collection and report generation via ThingSpeak. There was a focus on improving the system's reliability, allowing consumers and suppliers direct and easy access to consumption monitoring, and the NodeMCU ESP8266 WiFi module was chosen as the operational core of the system.
