Implementación de un módulo domótico enfocado a la eficiencia energética de hogares, utilizando sensores y actuadores convencionales controlados inalámbricamente por una tarjeta de desarrollo.

Abstract

The objective of this work was the creation of a home automation module to measure the consumption of home electrical energy and reduce it through the application of concepts, strategies of energy efficiency and the use of IoT technology. The module was divided into stages, starting with the measurement stage, sending stage, display stage and activation stage, they were used sensors to measure voltage, current, temperature, motion and light, the data obtained were entered in the analog and digital inputs of the development cards of the Arduino family, ESP01 wireless communication boards were used at the sending stage and NodeMCU that connect to the Ubidots server to store the measurement data of the sensors, from here you can interact with the information by creating events and dashboards. For the activation stage, circuits were created that activate remotely the devices connected to the electrical network of the home. A test of stability was carried out, where it was determined that the coefficient of variation does not exceed 1.293% as determines the INEN Standard, for which the module is stable and with little variance. To verify the reduction in consumption, the values of the CELEC EP spreadsheets were analyzed before and after the installation of the module, a 32% reduction in the value of the spreadsheet, the installation of the home automation module in the home made it possible to reduce electricity consumption and therefore the cost of the payroll through the control of lighting activities and ventilation. It is recommended to implement the use of voice commands as an alternative to remote activation of the home automation module.
