Smart Living

Τhis thesis is the development of an application - in the context of smart living technologies - that enables the user to monitor and manage specific resources with the help of sensors. In fact, monitoring is done remotely and the stakeholder can be informed about the status and availability, but also can configure various monitoring factors at any time.
Sensors (or simulated sensors) are used to achieve the object which we consider to be installed in a physical structure and send messages about the availability and status of resources to a server (broker) according to the mqtt protocol. This protocol is a publish-subscribe network that helps send messages between two devices, in this case it is used to send messages from sensors to a server, the broker. Then, our system (which consists of applications: one simulates the sensors and the other is the server of the system and is responsible for all the functions of the system) reads asynchronously the messages from the broker and saves or processes them. Another mobile application has been implemented that shows this information to the stakeholder, who can be informed of the availability or status of the resources he has chosen to monitor or even customize the features of the physical structure where the sensors are located. When implementing the components of this thesis we consider as an illustrative example, in order to understand the examples and explanations used throughout this paper, the physical installation of a kitchen, considering that we install sensors in all possible sections of a rack and monitor the various products available in these sections.
The results of the implementation of the system that we have described relate to the ability of the user to be remotely informed about the availability and status of the products he is monitoring, the ability to prevent shortages by delivering updates to the user if the product is nearing depletion, and the ability to extract statistics data to help better manage resources. We consider that the system we are describing can have many applications, such as for an individual (examples include: people interested in introducing the idea of smart living into everyday life, people with disabilities, older people who do not have a caregiver, etc.) or for professional use (examples include: large businesses with warehouses, supermarket shelves, and more).
