Desenvolvimento de um sistema autônomo baseado em arduino para avaliação de desempenho e otimização de dessalinizadores solares.

Abstract

This course conclusion work aims to develop an Arduinobased autonomous system for monitoring and controlling active solar desalinators. The system was developed to enable the user to map values of important quantities in the study of solar desalinations and to control the active part of designators. The ATmega 2560 works as a data processing center, communicating between modules and sensors to enable measurement, storage and control of the solar desalination device. To build the system, the methodology of progressing with the hardware and software design in parallel was used, as development progressed, carrying out empirical tests with the sensors to obtain data and survey curves. So, a system was developed that can measure 3 points of a solar desalination device, as well as irradiation and ambient temperature, making it possible to store the measured variables on a microSD card. In addition, the system has a control system that is composed of 4 relays and that can activate electrical elements that can heat the water. of the temperature sensors used as a reference. Another feature of the equipment is that the user can choose which temperature value will be used as a setpoint by the control system, thus enabling greater versatility of utility in each specific desalination device in which it is used.
