Controle fuzzy para ar-condicionado via mensagens MQTT.

Abstract

Currently in Brazil the consumption of electric energy in homes has experienced a significant increase due to the growth of the purchasing power of the middle class. This increase can be explained by the use of air conditioners and air conditioners, since these equipments represents a large portion of energy bill at the end of the month. Aiming for a solution to this problem, this work was carried out with the objective of controlling the air conditioning of an environment, aiming at the promotion of thermal comfort and consequently decrease of the energy consumption. For this, a control system was developed using fuzzy logic, values expressed linguistically, similar to human thought. The communication between the parts of the system is done by MQTT protocol, using IoT concepts. Tests performed at the UFCG demonstrated rapid response, accuracy and easy implementation of the controller. As well as the reduction of consumption of the controlled system compared to the uncontrolled, reduction of 40%.
