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. These dark tubes are also considered a concentrator of radiation and are used to increase the solar tracker robustness. That is to say, the night has come. 5). 2 Axis Solar Tracker A simple construction of a two axis Solar Tracker designed and constructed for Photovoltaic Systems – … on Introduction, Nice!! 7 years ago The PWM inputs of two servos are given from digital pins 9 and 10 of Arduino. This range is used to stabilize the controller and once the solar tracker is perpendicular to the sun, no further control is made. The top of the potential divider is 5 V, the ground is at 0 V, and the output of the voltage divider is connected to an analog input (, 0 for instance) of the microcontroller. https://www.browndoggadgets.comWe uploaded a new video with updated parts, laser cut files, and a custom PCB. Really cool. Hi, thank you very much for the idea. The PV voltage acquired through the analog pin A5 must be treated and used to compute the PV current and power. Best, what is the rate and power of servo motor which u have used.. can u give me some details.. i have to do this as mini project, Good luck with your project. 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. LDR light sensors were used to sense the intensity of the solar light occurrence on the photo-voltaic cells panel. Доброго времени! Heliostat Solar Sensor support structure, Reply In this case, the solar tracker must return to the sun’s rising position. designed a solar tracking system based on Arduino UNO with a Bluetooth radio module to get a real-time measurement of the output voltage of the solar panel … As presented, the entire structure has been manufactured using wooden plates, and it is clear that the all mentioned components have been used to build the solar tracker with manual and automatic modes (LDR sensors, Arduino Uno, Servo motors, potentiometer, pushbuttons, and the small PV panel). The LDR sensor circuitry is designed as a voltage divider circuit. Arduino Solar Tracker We will use LDR to sense the light and rotate the servo motors connected to circuit, to move the solar panel direction towards to light source. Two LDR’s (Light Dependent Resistor) are also connected to analog pins of the Arduino. 2. A push-button is connected to pin 11 to switch the potentiometer between the two motors, either it controls the left-right servomotor or up-down servo motor. Arduino Solar Tracker with ServoMotor. In this project, we are going to show you how to make an Arduino Based Solar Tracker Using LDR & Servo Motor. Arduino recommended input voltage is from 7 to … … 3. This can add up to 25% more energy compared with a fixed panel. :D. It's really helpful to get me started toward my other goals. A dummy solar plate is attached in parallel to the axis of servo motor and both the sensors are kept on the dummy solar … For automatic mode, the microcontroller converts the analogs values of LDRsensors (pins A0 to A3) into digitals. Moreover, we also determined the average radiation between the four LDR sensors and if this value is less than a little value (8: a value which has been adjusted and tested practically and is returned when the irradiation is null). 4. I adapt it for 2 LDR: // (*) según el montaje se puede modificar// (*) must be modified according to the assembly#include // include la libreria Servo.h Servo horizontal; // se nombra el servo horizontalint LDRl = 1; // pin de la fotoresistencia leftint LDRr = 2; // pin de la fotoresistencia rightint delayPot = 4; // pin del potenciometro 10k para la velocidadint tolPot = 5; // pin del potenciometro 10k toleranciaint paso = 2; // estos son los grados de cada movimiento(1, 2 or 5) (*)int servoh = 90; // initial positionvoid setup(){ Serial.begin(9600); horizontal.attach(9); // se define el pin del servo horizontal.write(servoh); delay(1000); horizontal.write(0); // this line helps to a inicial test delay(1000); // this line helps to a inicial test horizontal.write(180); // this line helps to a inicial test delay(1000); // this line helps to a inicial test horizontal.write(servoh); // this line helps to a inicial test delay(250); // this line helps to a inicial test}void loop() { int medidaLDRl = analogRead(LDRl); // medida LDR izquierdo (left) int medidaLDRr = analogRead(LDRr); // medida LDR derecho (right) int delaytime = analogRead(delayPot)/2 + 100; // potenciometro velocidad (*) int tol = (analogRead(tolPot)+10) / 10 + 10; // potenciometro tolerancia (*) int diffhoriz = medidaLDRl - medidaLDRr; // calcula la diferencia entre left and rigt if (diffhoriz < -1*tol || diffhoriz > tol) // check if the difference is in the tolerance else change horizontal angle { if (medidaLDRl > medidaLDRr) { servoh = servoh - paso; if (servoh < 0) { servoh = 0; } } else if (medidaLDRl < medidaLDRr) { servoh = servoh + paso; if (servoh > 180) { servoh = 180; } } else if (medidaLDRl == medidaLDRr) { // nothing } horizontal.write(servoh); } delay(delaytime);}, Nice Explanation Engineer!I’ve also created a solar Tracker which is operated without Arduino.It consists of only this components –LDR ModuleL293D Motor Driver ModuleDC Motor 30 RPMSolar Panel (Any ratings)Checkout the Full tutorial Here – http://alphaelectronz.com/solar-tracker-without-arduino/, Question The rotation movements occur in two axes, in azimuth from east to west according to the daily sun's path and in elevation from south to north according to the seasonal sun's path. A servomotor (MG996R) to control the solar tracker according to the vertical axis, which is the left-right servomotor. I have not been able to pursue this one so not much more to add. For example, if the sun’s rising position can be reached by setting 0 degrees in the left-right servomotor, and 30 degrees in the up-down servomotor. Arduino Solar Tracker – Working. It is composed of the PV panel, the left-right and up-down servomotors, and four LDR sensors. From Figs. That is to say, the night has come. Did you make this project? Then, to establish the communication between the board and Excel, we just need to open the Spreadsheet and defining the connections settings (Baud rate and port) in the PLX-DAQ window (Fig. The test bench has two modes: manual and automatic. For the horizontal axis, a bearing is fixed in parallel with the up-down servomotor for better flexibility. I'm a student in Belgium. Except time and money. Another development, I used a Makerbot Replicator to print a replacement for the foam core sensor holder. The test bench has two modes: manual and automatic. Now I'm going to try to use it to build a Solar Forge and or a Solar Sand Sinter 3D Printer. The latter will continue to rotate until the difference result is in the range [−10, 10]. Furthermore, the PV voltage is measured through the analog pin A5 of the Arduino, then the PV current is calculated since the resistor of the load is already known. 3 presents the electronic circuit of the proposed testbench.
