Sistema modular de telemetría para medición de parámetros en el hogar, basado en el internet de las cosas

Abstract

In this article, we discuss the development and results obtained in the design of a modular telemetry system for measurement of different parameters at home and having the possibility of knowing and monitoring the data remotely through a mobile application. Using instrumentation, it is planned to measure electrical energy consumed at home in kWh, the amount of water consumed, pressure and presence of LP gas, interior lighting, temperature and the energy generated by a photovoltaic panel interconnected to the electrical grid. The architecture proposed for the development of this application is based on the three-layer model of the IoT (Internet of Things), making use of a microcontroller based on the ESP8266 chip called NodeMCU®, the reading of the parameters proposed above is performed, and these data are transmitted through a Wi-Fi (Wireless Fidelity) communication protocol called Websockets®, the data is sent to a database on the internet using Firebase® service, later this database communicates with a mobile application in which displays the data collected by the microcontroller in a graphical interface programmed with Android Studio®. The user will be able to monitor the different parameters in real-time and based on his criteria, take preventive and corrective actions for the conscious use of his energy resources.
