Arduino Solar Tracker With Dc Motor
Arduino solar tracker the proposed test bench is presented in fig.
Arduino solar tracker with dc motor. The energy monitor uses 2 current sensors to measure the current. What is the rate and power of servo motor which u have used. The code essential measures the light intensity from both photo resistors it then compares the two to see which is receiving more light. Below is the program that will interface servo motor ldr with arduino for solar tracking.
It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel. Arduino recommended input voltage is from 7 to 12 volts but you can power it within the range of 6 to 20 volts which is the limit. To switch between the two modes automatic and manual a push button is used. If the difference is greater than a small threshold then the arduino tells the servo to move in that direction to direct the panel towards the light source.
Copy this code and upload it to your arduino board. It searches for the brightest light source like the sun. So i ve made a solar tracker using an arduino and servo motor. It is based on a solar tracker that can rotate automatically to track the sun with the help of four ldr sensors and two servomotors sm1 and sm2 or manually using a potentiometer.
In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. 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. Here is the link to download the solar tracker code. Try to power it within the recommended input voltage.
Can u give me some details. In this post i am going to talk about the solar tracker which i ve made using a arduino uno and sg90 servo. Photovoltaic powers the solar tracker no external source needed. This solar tracker system uses the arduino uno board a servomotor 2 ldrs and 2 resistors to rotate the solar panel towards the sun or a source of light.
I have to do this as mini project. We used 2 solar panels of each 12v 150w which will bring the total to 300w.
