Abstract

This article presents the design of a prototype for the monitoring, recording and control of the most representative physicochemical variables in fish farming such as dissolved oxygen, temperature and pH in a tilapia culture. This in order to optimize the living conditions of this fish species and counteract the negative effects such as increased mortality in the production process. For this, the system has a temperature sensor DS18B20, a commercial sensor for pH measurement SEN0161 and a dissolved oxygen detector of the company Atlas Scientific. These will be responsible for obtaining the respective values in real time of each of the physicochemical variables. The system also has a control stage managed by a simple plate computer or commonly known as Raspberry Pi, which fulfills the task of acquiring all the information. The prototype also has a local application developed in Qt Designer whose objective is to act as a graphical interface for the visualization and constant monitoring of the measurements made by each of the sensors. Also it has a server that stores and organizes remotely on a page web all the information obtained so that the user has easy access and can monitor in real time the tanks with tilapia.
