การพัฒนาระบบตรวจวัดคุณภาพน้ำโดยใช้ IoT เพื่อติดตามคุณภาพน้ำผ่านแอปพลิเคชัน (Development of Water Quality Measurement Systems Using IoT to Monitor Water Quality through an Application)

Abstract

 The objective of this research is to develop water quality measuring tool and information system showing water quality measurement results. The research sample comprised two sample groups. The first group was the group for evaluation of the efficiency of water quality measuring tools and information systems showing water quality measurements, consisting of 6 representatives from communities and academics from higher education institutions, obtained by purposive selection. The second group was the group for evaluating the satisfaction with the use of water quality measuring tools and information system showing water quality measurement results, consisting of 30 representatives obtained by simple random sampling. Data were collected by interviewing and the use of questionnaires on satisfaction with the tools and the system. The data were statistically analysed with the use of frequency, percentage, and t-test. The results of this research show that the water quality measuring tool can measure the pH value, temperature and turbidity. The results of the performance measurement of water quality measuring tool by comparing the differences between general tools and water quality measuring tool show that there is no statistically significant difference at the .01 level. Also, the information system showing the water quality measurement results can present the data in the forms of tables and graphs and can be used for trial with the samples with the overall satisfaction rating mean of 4.32, which is at the high level.
