Wind energy, even though abundant, varies continually as wind velocity varies in magnitude and direction over a time period. As the wind turbine’s rotation depends upon the availability of wind force and if the wind turbine axis is not completely aligned with the wind velocity a significant amount of wind energy is left un-extracted. Our idea is to implement the object sensor in windmill which would sense the wind’s direction and align the turbine axis with it. At present they are using anemometer for controlling the direction of the windmill. Compared to that our system would be more effective for controlling the direction, while the anemometer is replaced by object sensor. The microcontroller directly communicates with the object sensor and it is programmed in such a way that it can trace out where the wind flow is occurring. And on the basis of that, the microcontroller would rotate the wind turbine hub using servomotor or stepper motor.
