Voltage Sensor Module 0-25V - Analog Input for Arduino
Voltage Sensor Module (0-25V) – Analog Output for Arduino & Raspberry Pi
The Voltage Sensor Module is designed to measure DC voltages from 0 to 25V using a resistive divider network. It outputs a scaled analog voltage (0-5V) proportional to the input, making it ideal for microcontroller-based monitoring systems. Perfect for battery level tracking, power supply monitoring, and DIY electronics projects.

What You Can Build With This
- Build a real-time battery voltage monitor with an Arduino Nano and OLED display
- Create a solar panel output logger using an ESP32 and cloud dashboard
- Design a variable bench power supply with voltage readout on a 16x2 LCD
- Integrate into an overvoltage protection circuit with relay cutoff at 24V
Compatibility
This sensor works with any microcontroller that has an analog input, including Arduino Uno, Nano, Mega, ESP8266, ESP32, and Raspberry Pi (with external ADC). It accepts 0-25V input directly; no external components are needed for basic measurement. Common pairings include the INA219 for current sensing alongside voltage.
Wiring Notes
Connect VCC to 5V, GND to ground, and S (signal) to an analog input pin like A0. No pull-up is needed; ensure the input voltage never exceeds 25V to avoid damage.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, connect the S pin to any analog input on Arduino boards (5V logic). The output voltage range is 0-5V, matching the ADC reference.
Can I measure AC voltage?
No, this module is designed for DC voltage only. For AC measurements, consider a transformer or dedicated AC sensor module.
What is the accuracy?
The module has an accuracy of ±0.2V typically, depending on ADC resolution and supply voltage stability. For precise readings, calibrate using a known reference.
