In the last few decades, there has been an increase in the use of digital devices by the people as a way of facilitate their day-today tasks. Several new devices have been developed for the control and automation of residential environments, thus emerging the smart homes concept that is strongly linked to the Internet of Things. Such devices are used for safety, decoration, child care, domestic management, among many other applications, and are implemented using many wireless communication technologies, data storage, sensors and actuators. In this scenario, Bluetooth low energy technology has played important role. Recently, Bluetooth 5.0 emerged with significant improvements, including twice the speed and four times the range compared to the previous generation. Also, it is possible to keep the Bluetooth on for longer time, since consumes less energy than generation 4.0. This enhanced characteristic has stimulated the use of this technology in home automation applications, and so, we explore this technology in this work. This work is aimed to develop a home automation system, consisting of a central hub and two peripheral modules, being them a Smart Power Plug and a LPG Sensor. The communication between the devices was developed using the Bluetooth ® 5.0 communication protocol and the data were stored in a real-time database of Firebase ® , which also communicates with an Android application. For this purpose, a NodeMCU ® development kit and some boards containing the CC2640R2F microcontroller were used. The results obtained so far, are quite promising to be applied in home automation applications.
