Scheme and Creation of a Prototype for the Supervision of Lights and Electronic Devices with a PBX, Using a WLAN Solution Based on IoT

The domotic solutions that benefit households and many companies today depend almost entirely of an Internet connection. Sometimes it is not always possible to have a link or permanent access to the Internet. This project provides the basis to look for an alternative that facilitates the control and monitoring of lights and electronic devices through a telephone call, through the use of an IP PBX. This research exposes the guidelines and activities carried out for the design and implementation of a prototype for the supervision and monitoring of lights and electronic devices through a PBX, using a wireless solution based on IoT, which serves as a base for the search of technological solutions using platforms of access and development as Arduino and Raspberry, obtaining energy and economic savings. Likewise, seeks to optimize the variables of time, cost and benefit that can provide the communities the use of domotic systems, the use of the necessary resources provided by data networks and telecommunications to perform actions remotely. For this, VoIP systems are used, converting the Raspberry card into a PBX plant with the software on a server based on Asterisk and two extensions were configured with the SIP telephony protocol, one of the most used at a corporate level. With respect to IoT, its four pillars (People, Processes, Data and Things) have created the need to have a society that empowers the new generations of digital citizens who understand the emerging technologies offered by IoT, the impact it has on the community, the widespread adoption of the same and the correct application of the information captured. For the prototype, we have used components (sensors) that can work, or that can act as a starting point for an IoT solution.
