🔋 Voltage Sensor Module DC 0–25V – HD Version
Breadboard Compatible | Arduino Ready
The Voltage Sensor Module is a compact, cost-effective solution for measuring DC voltages up to 25V. Designed for compatibility with Arduino, ESP32, Raspberry Pi, and other microcontrollers, this module safely scales high voltages down to a readable 0–5V analog signal.
This HD (High Durability) version is built with better PCB quality and is breadboard-friendly, making it ideal for prototyping, student labs, and permanent embedded systems.

🔌 Pinout
[ VCC ] – Connect to 5V
[ GND ] – Ground
[ S ] – Analog Output (to A0, A1, etc.)
🧪 Example Application: Arduino Voltage Monitor
const int sensorPin = A0;
float voltage = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(sensorPin);
voltage = (sensorValue * 5.0 / 1023.0) * 5.0; // Multiply by 5 due to divider
Serial.print("Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(1000);
}
