Because of technological development in recent decades, it has become increasingly common to use smart devices in everyday life. The concept of pervasive computing explains this phenomenon by proposing to integrate the virtual world with the physical world, making technology dissociable and imperceptible to the development of people's daily activities. In this way, the concept of IoT (Internet of Things) has emerged, fostering a wave of upgrades in common devices that are used in our daily lives. Equipped with computing capabilities, devices now produce massive amounts of data, creating a favorable environment for applying big data techniques in the process of storing and analyzing data. Immersed in this context, this study aims to develop an IoT-based monitoring system that uses MQTT (Message Queuing Telemetry Transport) communication to establish remote supervision of any measurement device connected to the broker, storing samples of the measurement of electrical quantities in the Firebase Realtime Database to allow instant access to the data via a remote monitoring web page. The results have been demonstrated the effectiveness of the combination of the MQTT protocol, the ESP32 device, and the Firebase database through the analysis of processing time and efficiency in the storage of information.
