Projecto de uma instalação eléctrica residencial com automação baseada no microcontrolador ESP32 numa residência de 3 pisos

Abstract

The present work arises within the scope of obtaining a degree in Electrical Engineering from Eduardo Mondlane University. The work consists of an electrical installation project for a single-family residence with 3 floors. The work includes studies on the electrical installation and equipment to be installed and the protection devices against the adverse effects of electricity. It is planned for the electrical installation of lighting circuits, sockets for general use to power the various low-power loads, sockets for specific use to power the air-conditioning in the residence, an electric oven, water heater, washing machine, and water pump. The residence was also automated using the ESP32 microcontroller device for remote lighting control. The ESP32 was created by ESPRESSIF SYSTEMS and has been innovating in this area due to its integration with Wi-Fi, Bluetooth and the high processing capacity associated with its low cost. Therefore, for its application, the ESP32 microcontroller was used, together with its Wi-Fi functionality, which allows interaction with the Internet through the HTTP data protocol, from where the signal is received by the microcontroller, and this, in turn, activates a relay module for the respective commands. to switch on or off the circuits intended to control. A temperature and humidity sensor has also been integrated with the microcontroller, whose information can be sent in real time to the device and the reading can be done through the web application. In order to understand the automation functions of the microcontroller, it was programmed using an application created for arduino programming, the IDE SKETCHUPP, due to its relatively simple programming language, the CC+ language. The cost of equipment and labor was estimated in 368 576,403Mt.
