As the global demand for renewable energy sources continues to rise, wind energy has emerged as one of the most important and sustainable methods for generating electricity. Wind energy stands out for its ability to operate continuously compared to solar power, and it is particularly cost-effective in areas with consistent high winds. With advancements in technology, the cost of electricity generation from wind turbines has become competitive with traditional methods, further highlighting its global significance. To ensure the efficiency and longevity of wind turbines, it is essential to implement robust protection and monitoring systems. In this research, we propose the design and implementation of a control system using Arduino and the LM35 temperature sensor to monitor the temperature of the wind turbine generator. The system will automatically shut down the turbine when the generator's temperature exceeds 70°C, thereby preventing damage and ensuring continuous, efficient energy generation. The proposed system provides precise temperature monitoring and triggers a shutdown when necessary, with the potential to integrate a cooling system for enhanced performance in high-temperature environments. This research contributes to improving automated protection systems for wind turbines, enhancing the effective use of wind energy while reducing the likelihood of mechanical and electrical failures caused by overheating.
