Diseño y construcción de un sistema domótico para controlar dispositivos conectados mediante una red de sensores, a través de un servidor doméstico.

Abstract

In the present project a domotic system of hardware and software was developed, which will allow to automate a house, with the purpose of facilitating the daily habits of the user, in such a way that only with manipulating a PC or a cell phone can have the control of your home, of course, this would depend on the services that are scheduled and installed within your home. The objective is to have control of a home, through a wireless connection to manipulate electronic devices using mobile devices or a computer. For the realization of the project, electronic devices such as microcontrollers, sensors, actuators that will send information to the main server were used. The server will process it and issue orders to the different electronic devices, through the use of HTTP GET and HTTP POST requests; it should be noted that the system developed will work under a wireless communication (Wifi) technology. The main server will be installed in a Raspberry PI 3, which will be linked to a microcontroller called NodeMCU, this microcontroller will be programmed with several scripts, which will send the different requests to the sensors and actuators. The project was provide a friendly user interface, where the user can access from any web browser. This system had a user login, a lighting system, motion sensor, gas and smoke detector, blind control, and finally an audit system that will allow users to see the system, it should be noted that it also provides an administration interface. As a result, a secure and user-friendly application was obtained, with an administrative interface that will control electronic devices.
