The fundamental objective of this undertaking is to plan an extremely exact sun based tracker. The venture is isolated into two sections; equipment and programming. Equipment part for the most part made out of sun based board, two-DC engines with gearbox, LDR sensor module and electronic circuit. Programming part speaks to the reasoning conduct of the framework, that is the means by which the framework acting under a few climate conditions. In this work detecting of the sun position completed in two phases essential and auxiliary.
Essential stage or aberrant detecting performed by means of sun-earth relationship as a coarse change and second stage or direct detecting performed by means of set of LDR sensors as yield tuning to trims the azimuth and height points. On the off chance that the climate is overcast or dusty, the following framework utilizes essential stage or sun-earth geometrical connections just to recognize the area of the sun; so the framework tracks the situation of the sun in any case the climate condition. The vitality removed from photovoltaic (PV) or any sunlight based authority relies upon sun oriented irradiance.
For most extreme extraction of vitality from the sun, the sunlight based gatherer board ought to dependably be typical to the episode radiation Solar trackers moves the sun based authority to pursue the sun way and keeps the introduction of the sun oriented gatherer at an ideal tilt point. Sunlight based following framework enhances significantly the vitality productivity of photovoltaic (PV) board. In this paper, a programmed double hub sun based following framework is planned and created utilizing Light Dependent Resistor (LDR) and DC engines on a mechanical structure with rigging course of action. Two-hub sun based following (azimuth edge and also height edge) is actualized through Arduino UNO controller dependent on Sun-Earth Geometry. The outcomes showed that the programmed sun powered following framework is more dependable and productive than settled one.
