Solar Tracking System Using Ldr

In this article we are going to make a sun tracking solar panel using arduino in which we will use two ldrs light dependent resistor to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light advantage of this project is that solar panel will always follow the sun light will always face towards the sun to get charge all the time and can.

Solar tracking system using ldr. In this project we are going to use some light sensitive sensors like ldr to track the sunlight and direct the solar panels towards the areas that increase its efficiency. There are basically two types of arduino sun trackers. Dual axis solar tracking system to ensure maximum extraction of energy from the sun an automatic dual axis solar tracking system developed using arduino controller based on sun earth geometrical. We have designed a single axis solar tracking system.

The solar panel tracker is designed to follow the sun movement so that maximum light intensity hits on the solar panel thus increasing the power efficiency. One of them is the single axis solar tracker and the other is dual axis. This board was located with the pv panel to collect data for the solar tracking. In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor.

Department of mechanical engineering university of mumbai lokmanya tilak college of engineering koparkhairne. The position of the ldrs are critical here and the set of ldr which corresponds to this vertical plane movement is so positioned that it senses the sun light accurately and tries to keep the panel perpendicular to the sun rays by moving the motor in the appropriate direction through a definite number of stepped rotations. Single axis solar tracking system moves the solar panel from east to west in a day to point in the. In this article you will learn to make a dual axis solar tracker arduino project using ldr and servo motors in step by step manner.

How the ldr circuit works. In a nutshell this circuit is a voltage divider once the ldr behavior is known lower resistance with higher light incidence the ldr with higher light incidence shows the higher voltage with the maximum voltage limited on 5v to comply with arduino input.
