Solar Tracker Using Dc Motor Arduino

A dual axis solar tracker with photovoltaic was designed in order to follow the sun during the day.

Solar tracker using dc motor arduino.

And a micro servo motor sg90 to control the solar tracker according to the horizontal axis which is the up down servomotor. A solar tracker is a mechanical automatic device that through sensors can understand the position of the sun that thanks to the motors you can follow it so as to store more solar energy. To track the sun i used four ldc sensors and arduino compares the data from them to rotate the panel in the direction with the most sunlight using two dc motors one for each. Photovoltaic powers the solar tracker no external source needed.

Connect 5volt pin from the arduino to the lower horizontal row of the breadboard. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. The advantage of the servomotor is that we can control its stop run the direction of rotation and speed using a single low current wire connected directly to an output of the microcontroller without needing any drivers.

Circuit diagram the circuit design of solar tracker is simple but setting. Extend the 5 volt and gnd rows to the upper horizontal rows of the breadboard. Interfacing dual axis solar tracker arduino project using ldr servo motors. Solar tracker is a device which follows themovement of the sun as it rotates from the east to the west every day.

The mathematical simulation control of dual axis solar tracking system ensures the point to point motion of the dc motors while tracking the sun. Solar tracker using arduino. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. Diy solar tracker arduino project ita.
