The real reason for sun oriented following framework is to assemble most extreme measure of energy supply by methods for following the sun-powered panel. As soon as the framework is exchanged on, the sun-powered board goes to the underlying position, i.e. towards the east. There are four LDR which is set each in 45o to continue following of the sun from sun ascend to sun fall. When the light falls on the principal LDR, the flag will be sent to IC 89C51 microcontroller. This thus controls the stepper engine position i.e., to begin with, quarter 0-45o.
As the sun rises when the daylight falls on the second LDR i.e. second quarter 45-90o, naturally first LDR is put off and the second one gets on. The flag from the second LDR goes to the IC and thusly goes to the stepper engine to change its position, i.e. 45-90o. A similar procedure goes ahead till the sun tumbles down. So we can track the sun consistently. The electric vitality hence got from the sun based cell goes to a capacity cell/battery and it is put away. At the point when this vitality is required it is gotten by utilizing an inverter. It is likewise modified, with respect to the season of load on and stack off. Here the heap is water pump for inundating the field.
