Diseño e implementación de control domótico (con sistemas embebidos) para conectarse con aplicaciones adaptivas basados en IOT

Abstract

Nowadays, home safety is one of the most critical issues in society, which is why traditional methods such as fencing or raising walls in structures are no longer enough. The purpose of this technical project was to present a viable option to the end users who may require to know the current state of their home from anywhere and at any time via the Internet. In addition to this, a home domotic control system that somehow reduces energy consumption was proposed. In order to develop this proposal, principles related to Domotics, Embedded Systems and Internet of Things were investigated to foster the design, development and implementation of the product. Thereby, development boards, sensors and employed actuators were analyzed and compared by means of prioritization methods which is a recommended technique for decision making in these kinds of procedures. These elements became integrated according to the intended requirements, designing hardware blocks with wireless communication that were later implemented in an experimental prototype. By comparing evidence between HTTP, WebSockets, MySQL and MQTT protocols, it was demonstrated that MQTT was ideal with 96% effectiveness to establish an immediate response to each user request, besides being the only one that has "QoS" specifically. Finally, once the prototype has been implemented and verified, its energy autonomy stands out because it reduces light consumption by 43,33 % per year; furthermore, it incorporates advantages at the moment of preventing the user in case of an intrusion thanks to its 24/7 availability.
