    Currently, the use of wind energy as a source of pollution-free energy is an attractive alternative. For a wind farm to work properly, it is necessary to take different measures (wind speed, direction, etc.) with the intention of optimizing the energy generation process. In addition, it seeks to protect the structure of the wind turbine before adverse environmental conditions, such as continuous gusts of wind or with variations where the structure can reach a resonance regime. One of the approaches to reduce the cost of corrective maintenance is the supervision of the state of the blade for the early detection of faults. The purpose of this project is the design and implementation of an instrumentation system to measure the effort in the blade of a wind turbine using voltage meters. This in order to monitor the structural health (avoid fractures or ruptures), looking to increase the life of the blade in a wind turbine. For which, a wind turbine was implemented as a prototype. In this structure are the main cable and wireless communication modules and the instrumentation system. The latter processes the measurements that reflect the strain gauges placed on the blade in question. In addition, of two secondary modules, the first one processes the voltage obtained by a generator, due to the movement of the blades. The second module is a tripping angle control; this has the purpose of modifying the wind speed of a fan. That will be used as a disturbance in the blades
