DISPOSITIVO DE BAIXO CUSTO BASEADO EM INTERNET DAS COISAS PARA MONITORAMENTO REMOTO DA QUALIDADE DE ÁGUA DESTINADA AO CONSUMO HUMANO

Abstract

ABSTRACT

This experimental research consisted of the application of a continuous water quality monitoring system, using real-time data transmission technologies, with a focus on cost reduction and minimizing operational errors. Monitoring devices were installed in four municipal early childhood and elementary schools in the municipality of Itabaiana, Paraíba, allowing the hourly analysis of parameters such as pH, temperature, total dissolved solids (TDS), conductivity, salinity, color, and turbidity, between July and December 2024. The data, automatically transmitted to a centralized database, were subsequently analyzed with Python language tools, enabling the identification of trends and patterns, as presented in the results section. The water quality assessment followed the limits established by Ordinance No. 888/2021 of the Ministry of Health. The monitoring system was developed based on the Arduino IDE platform and ESP32 module, standing out for its simplicity, efficiency, and scalability potential. The research received technical and financial support from the company CONSTA SERVIÇO DE ANÁLISE DE ÁGUA LTDA. Finally, the performance and costs of the developed device were compared to similar solutions available in the Brazilian market, such as the Aquaread AP 7000 Multiparameter Probe, sold by AgSolve Monitoramento Ambiental LTDA.
