The overall project is a system (hardware + software) that allows monitoring and control in a building / office different security systems, energy, communications, home automation, PKI's overall business that will increase all the efficiency of the building and the business and ensure the continuity of it. My participation in this Project will mainly focus on the development of hardware components, monitoring and control system (home automation, energy, safety control elements ...) and software components for integration with the platform in general. The technology used is Arduino, as it gives us all we need and requires, and also the possibility that if the situation needs it, to expand the number of sensors or devices that we interact autonomously. Specifically, our system will consist of two current sensors using two clamps ampmeter, to take care of reading the power consumption of the electrical network installation. Besides it also will control the charging and discharging of the battery that provides all the energy used in the complex. This is important since because it is necessary to control the activation of the generator that powers this, which gives tension to the facilities. Harnessing the potential of arduino, we will add a small system that act as "ring" to open the door of the company for take control of the acceso n the building, and also to explore all the possibilities that this device provides. We will study the possibilities of communication that has Arduino whith another plattforms and compatibility with technologies and languages such as PHP, MySQL, Asterisk, etc..
