Development of an automatic shutdown system for lighting and air conditioning by using Esp8266 to meet energy efficiency requirements in buildings

The energy efficiency is a subject that has been discussed worldwide. The technological advances allow the production of equipment that consumes less energy than old ones that perform the same work. Research on energy efficiency in buildings has gained a lot of attention lately and it can be optimized by evaluating parameters such as the installed equipment, the physical construction of the building or the habits of users. This article studies the construction of a system using the Esp8266 microcontroller, the Node-RED platform, among other devices. This system was based on RQT-C manual to provide an automatic shutdown of the lighting and air conditioning systems. It was installed at a research laboratory at Federal Institute Fluminense campus Campos Centro. The results obtained in 30 days after the equipment installation shows that approximately 20% of the energy was saved when it compared to the same period without the system.
