Projeto Ubique: sistema de monitoramento e controle de ar-condicionado

Abstract

This paper seeks to solve the excessive energy consumption related to the nonpower off and malfunction of air conditioners of the Centro de Informática. With the observation that the devices stay connected for a long time without the existence of someone inside the enviroment, and the increase in the electric energy price, it was veri ed the possibilitty of building a system that would be able to control the air conditioner remotelly or locally. The paper was developed through the creation of a printed circuit and the use of electronic components, sensors and a microcontroller board for information management and comunication with the internet, via wi connection and MQTT protocol. The results obtained in the tests demonstrated the feasibility of using the device and the system in a satisfactory and low cost way, in order to be used to reduce the consumption of electric energy.
