Implementación de un sistema autónomo inalámbrico para la alimentación de tilapia, basado en supervisión de variables climáticas y control de calidad de agua.

Abstract

An autonomous wireless system for the feeding of tilapia was implemented, based on monitoring of climatic variables and water quality control. The proposed project consists of two parts: the feeder and the positioning system, being easy to install and operate; with the presented prototype it is expected to have a social and economic impact on the production of tilapia culture, where conventional methods can cause waste of balance, agglomeration of fish at the launching points and a greater presence of personnel to control water quality and feeding at different times with different types of balancing and in different quantities. The feeder consists of a photovoltaic system, a touch screen to configure the power parameters, a set of sensors that determine the percentage of balanced in the hopper, the level of dissolved oxygen in the water and the presence of rains; a notification module through text messages and telephone calls, a set of actuators that allow extracting, dissipating the balance and activating an aerator to raise the levels of dissolved oxygen, all controlled from the arduino mega 2560. The positioning system counts with a control board, an actuator and a pulley system to carry out the transfer. From the tests carried out, it was found that the feeder doses the amount of balancing desired up to a maximum of 30.9 kg and that the positioning system has an average error of 2.8 s of transfer time. It is concluded that the prototype is an automatic and autonomous feeder that considers the quality of water, climatic variables, type of balance and schedules for feeding tilapia. It is recommended to incorporate a storage system of balanced on the edge of the pool that supplies food to the prototype automatically.
