The Development of Embedded Systems for Automatic Water Quality Measurement via Online Networking.

Abstract

This objectives of this research were (1) to develop an embedded systems of automatic water quality measurement via online networking for farmers in a fish cage area, (2) to test performance of the system, and (3) to explore user satisfaction towards the system. In order to explore the performance of the system, this research compared the water quality measurement between the expertise and the system. The measurement included three parts which were (1) dissolved oxygen (2) pH and (3) temperature. In order to collect the data of water quality, date, time and location were controlled. The One Way ANOVA was used to determine whether there are any significant between performance of the expertise and the system. In order to explore user satisfaction, the data were collected from 31 fish farmers by purposive sampling. The results found that there are 3 parts of system development (1) automatic water quality measurement system (2) water quality report system (3) water quality notification system. The performance of the system showed that the water qualities measured by the experts and the system is no statistically significant difference at level 0.01. Moreover, the users had their overall high satisfaction value at 4.09 level.
