Solar Tracking system
The Project Entitled “Solar Tracking System” is used to trace the path of the sun and to position the Solar panel according to that .The system uses Microcontroller and a stepper motor for the above purpose . The stepper motor controls the panel direction.
The intensity of the light is sensed by using array of LDR’s the light sensing device the characteristic of LDR is to change its resistance according to the intensity of the light ,for example if the light intensity increases the resistance decreases and vice versa for other condition.
The array sensor value is converted into digital bits, the bits are sent to the microcontroller. Calculations are performed inside the microcontroller according the value given by the sensor.
By manipulating the value the value the controller controls the step angle of the stepper motor. The sensors are placed in such a way the if follows the path of the sun.
The placing of the sensor plays an important role in the system if the path fails the whole system will be disturbed. The motor angle is also sensed such that it must have ability to pull that much heavy load of the solar cell.
The system can be used in places where more current production is needed. The project can be advanced in future according to the user whishes.
STEPPER MOTOR:
It is a type of motor, which is digital i.e., it rotates according to the data given by the microcontroller the need for going for stepper motor is that the accuracy will be while comparing with normal motors.
