The present degree project has the objective to follow up the Mechatronic Design process carried out for the implementation of an automated monitoring and control system of the necessary physical-chemical conditions that should be considered in a pond dedicated to the production and breeding of fish; in terms of optimizing fish production in the Valle del Cauca, and, particularly, in the municipality of Tuluá. Through a wireless network system constituted by nodes such as: control, acting and sensing, intelligent solutions are generated to problems in branches of the rural sector that were not previously contemplated for the development of automated products. For this, a system based on microcontrollers of the ATMEL and XBEE family is used, given the connection by radiofrequency and its programming by Free Software (as main characteristic), together with features such as: low energy consumption, easy acquisition and manipulation of variables, easy deployment and generation of environments (for the development of constant workspaces and in real time) is achieved as a final result a complete system of sensing and performance that manages to comply with Online monitoring of a fish culture based on optimize the times of production, development and care of the fish farming activity
