This Diploma Thesis deals with the implementation of an effective remote management system of a greenhouse. At the beginning of the bibliography there is a short historical review of greenhouse systems and how they have evolved over the years. In addition, some basic functions that a greenhouse should perform are listed. Then, reference is made to the corresponding papers and publications to date, so that it can be seen that the system developed offers more possibilities and innovations. Then, a detailed presentation of the MQTT protocol is given, as well as its comparison with other communication protocols. Below is an extensive analysis and explanation of the sensors, the individual components, as well as the development boards that were used to implement the system. Then follows the design and programming of the electronic circuit which is the most important chapter of this thesis. The operating system (front-end and back-end) is also presented, which is an equally important chapter. More specifically, the website of the system is presented, where the greenhouse is managed from there (monitoring of measurements and activation/deactivation of functions). Finally, the conclusions as well as the future extensions-improvements of the developed system are presented.
