This project analyses the different composting techniques existing nowadays and proposes a variant. This variant is going to be proved in a prototype. Humidity and temperature will be the sensed and controlled variables. Depending on the value of these parameters, the prototype will actuate to adjust them to the user‟s guides. This project gives a guide of the optimal temperature and humidity values of the whole process, but the prototype has been designed to permit variations of the process, so this is not only a prototype for the values gives, but a prototype for new experiments and new values First of all, the state of art and the composting process will be analyzed. Composting is a biological natural process that transforms organic waste to natural fertilizer. This process can be improved to get better material in less time. This deals us to the most important part: the control of the material to maintain it in the most proper condition. This report is divided in several parts: first of all, an introduction to the composting process and the state of art; then, the prototype will be explained; then all the hardware used for this project will be described; then there is a special mention to the PIC software and the PC software the prototype uses. At last the results of the tests performed and the conclusions and future ways of developing are shown.
