Photovoltaic powers the solar tracker no external source needed.
Arduino solar tracker using dc motor.
Below is the program that will interface servo motor ldr with arduino for solar tracking.
Drop a comment below if you have any doubts or queries.
Circuit diagram the circuit design of solar tracker is simple but setting.
Finally we have completed interfacing dual axis solar tracker arduino project using ldr servo motors.
And a micro servo motor sg90 to control the solar tracker according to the horizontal axis which is the up down servomotor.
In this project an arduino nano is used which works as a controlling unit.
We hope you found this project useful.
In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.
It searches for the brightest light source like the sun.
Now you can use this project to track the solar panel and increase its efficiency by 40.
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.
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 axis and motor driver.
Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.
Two ldr s light dependent resistor are also connected to analog pins of the arduino.
We ll do our best to answer your questions.
Can u give me some details.
I have to do this as mini project.
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.
A dummy solar plate is attached in parallel to the axis of servo motor and both the sensors are kept on the dummy solar plate as shown in the figure below.
What is the rate and power of servo motor which u have used.
For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller.
It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel.
Usually the servo has a yellow wire that is used to control the rotation and it must be connected on pin 9 on the board.
