Equipamento de baixo custo para monitoramento de pressões em sistemas de abastecimento de água / Low cost equipment for monitoring pressures in water supply systems

RESUMO A importância de se monitorar as pressões no sistema de abastecimento de água aliada ao alto custo de implementação e manutenção de dispositivos capazes disso corroboraram ao objetivo deste estudo. Sendo assim, buscou-se desenvolver um equipamento de baixo custo para monitorar a pressão da água. Para isso, produziu-se 15 MPR dataloggers, custando R$ 208,15 cada, que foram aferidos com um equipamento comercial. Os equipamentos foram instalados em residências de distintos perfis de consumo e altitudes do município de Lucas do Rio Verde, no estado de Mato Grosso, por 43 dias. De modo geral, os resultados obtidos foram satisfatórios, promissores e demonstraram o equipamento robusto e preciso, com R2 de 0,9986 quando comparado com o equipamento comercial, além de ter sido possível avaliar o sistema de abastecimento da cidade e as intervenções necessárias.

ABSTRACT The importance of monitoring the pressures in the water supply system combined with the high cost of implementation and maintenance of devices capable of this, corroborated the objective of this study. Therefore, we seek to develop low-cost equipment to measure water pressure. For this, 15 MPR dataloggers were produced, costing R$ 208.15 each, calibrated with a commercial equipment. The equipment were installed in residences with different consumptions profiles and altitudes in the municipality of Lucas do Rio Verde, Mato Grosso, for 43 days. The results obtained were satisfied, promising, and showed that the equipment is robust and precise with a R² of 0.9986 when compared with the commercial equipment, in addition to being possible to evaluate the city's supply system and the necessary interventions.

Application of Arduino Open Source Hardware in Practice Teaching of TCM Informatics / 中国中医药信息杂志

This article briefly described the existing problems in talent training of TCM informatics, conducted discussion according to discipline personnel training practice teaching mode, proposed to introduce Arduino open-source hardware into TCM informatics teaching, try to carry out practice exploration for existing classroom and experiment teaching, and proposed relevant suggestions to promote learning interest of students and improve their application ability, with a purpose to further improve the practice teaching mode of TCM informatics, cultivate "TCM+informatics" compound and application talents to promote long-term development of this discipline.
