In this study the design and implementation of a smart peephole prototype is explained within the concepts of the Internet of Things and Domotics. The system implemented intends to partially automate the daily action of reaching the home door, check through the peephole the outside, and open the door. This is done by replacing the peephole for a camera and controlling the door using an electric door lock, and both components are managed through an Android mobile phone application. In first place, a brief description and the current state of the technologies involved in the study are explained. In second place the basic concept of the product is defined. It includes the first approach of the system, where the main parts of the project are identified. Then the communication protocols used for every connection are compared and selected, since different communications have to take place to perform its activity. The hardware requirements to achieve the product functionalities are also described and studied. Then, the entire development of the prototype is explained step by step. Different hardware options to implement the prototype are also compared and selected. And finally the software and firmware of the different components, which includes a microcontroller, a single board computer and a mobile phone, is developed and explained. Finally, the budget of the study and an environmental study are also exposed at the end of this document.
