Estudo e desenvolvimento de protótipo para automação residencial

Abstract

Home automation (Domotics) is increasingly present in people's lives and is already a reality in several Brazilian homes with differentiated solutions aimed at the needs of each one. From load control, sensors that send notifications to smartphones, to devices that can be programmed by time. This work presents a proposal for a micro controlled system to automate a home. Using low-cost components, we tried to demonstrate a general application on automation: controlling loads and receiving information from sensors. The prototype is based on three elementary components, a smartphone that controls load and receives information, a control center, and endpoints (loads or sensors) that are responsible for sending and receiving information. The communication of this prototype becomes real through radio frequency, that is, the communication between central and endpoints. For this purpose, functional testing, construction, verification tests, cost list were necessary. The purpose of this work is to encourage and resume the discussion of systems related to home automation, as well as provide content so that more people have access to this technology and are inspired to create their own solutions. With this work, it was possible to add knowledge in the home automation environment, as well as to develop the prototype, carry out the necessary tests, analyze the cost-benefit and seek new specific applications for the study of home automation.
