The Design of real time monitoring Device for Water quality of aquaculture Farm based on the single chip Microcomputer

Abstract

With the rapid development of social science and technology, people's living standard is increasing day by day. More and more modern people are eager to be able to use intelligent devices to replace artificial detection, which leads to more and more intelligent requirements for water quality monitoring. This paper aims at the problem of loss which caused by the deterioration of the water quality of the farm, so a remote monitoring device for monitoring the variation of water quality parameters is proposed and designed. The device can collect dissolved oxygen, pH value, temperature and other parameters of aquaculture water in real time, and the collected water quality parameters were analyzed and showed  when the variation of water quality parameters was more than the limit value,  then the device sends out sound and light alarm signal, so as to be able to deal with it in time and reduce the loss . The device has the characteristics of strong function, low power consumption, easy to carry, low production cost, stable performance and so on.
