In this document, the results of the development of a prototype for temperature and pH monitoring in the fish farm of the Francisco de Paula Santander University, Ocaña, is detailed, in order to provide an improvement to the processes related to the care of the environment of the fish in the fish farm, for this purpose, the Internet of Things is used, focused on agriculture, this has methodologies, materials and technologies that are analyzed in this document to select the most suitable for the development of the prototype and the points to consider for its implementation. Given that the application of a system focused on the problem expressed in the document can improve the quality of life of the fish not without first solving problems surrounding the internet of things focused on agriculture, as they are the power supply in rural areas and the creation of devices resistant to natural environments.
