Solar Voltage Tracker Using Arduino
step by step guide voltage monitoring system using arduino
Introduction
in this article, we measure the solar power monitoring system using Arduino. we measured the parameters like solar panel voltage, Temperature, and Light intensity. Here we also discuss all the components which one we used in this project.
In This circuit, we measure all parameters in analog form we need to first convert into digital format and we take reading in the serial monitor and 16×2 LCD Display.

Circuit Diagram
16×2 LCD is connected to the Arduino Nano
- LCD RS pin: Connected to digital pin 12 of the Arduino Nano.
- LCD Enable pin: Connected to digital pin 11 of the Arduino Nano.
- D4, D5, D6, and D7 pins are Connected to the 10, 9, 8, and 7 digital pins of the Arduino Nano.
LM35 Sensor measures temperature in degrees Celsius.
- It is connected to the Arduino Nano analog pin A6 to read the temperature values.
- The LM35 provides an analog voltage output proportional to the temperature.
The voltage is then calculated using a voltage divider circuit with resistors R1 and R2.
- R1: This resistor is connected between the voltage sensor output and the ground.
- R2: This resistor is connected between the voltage sensor output and the analog pin A0 of the Arduino.
Voltage = (Analog value/resistor factor) * Reference Voltage
Analog Value= Analog Output of Voltage Divider
Resistor factor= 1023.0/(R2/R1+R2)
Reference Volatge= 5V
Take resistor value
R1= 10k
R2= 1k
- Resistor factor= 1023.0 * (1000/1000+1000)
- resistor factor= 1023.0 * 0.5
- resistor factor= 511.5 for up to 10 v
Temperature Sensor = Analog Value * (5.0/1023.0)*100
The LDR Sensor is used to measure the ambient light intensity.
- It is connected to the Arduino Nano analog pin A5.
- The LDR Sensor resistance changes with the amount of light falling on it, and this change is used to calculate the light intensity.
RL= 500/Lux
The output voltage of this circuit can be calculated
- Vout= 5 * RL / (RL+3.3)
- RL is Load Resistance
Lux Formula = (2500 / Vout – 500) / 3.3

Project Working
Here we show the solar panel voltage is 16×2 LCD Display and the solar panel is small that’s why it shows the voltage of 6.13v Only.
Now we connected to the LM35 Sensor And LDR and then you show all reading in the 16×2 LCD Display.
