This project is designed to make a fully-equipped security system capable to be focused to different dangers, adapting itself to specific objectives. It is going to encompass a large range of possible hazard points as the steals, the fires and the gas contaminations. All of these will be tracked by different kind of sensors, managed by an Arduino based PLC. The data is going to be monitored by several PC Panels and a MQTT Server which will provide the possibility of the simultaneous connection of distinct devices. It will provide a 24/7 backup, saving the data in the SD card and sending it to the Server through an optimized and secure method called FTP.
