Overview

Monitor DC voltage easily in your electronics and embedded projects with the Voltage Detection Sensor Module 25V. This compact and practical module is designed to detect and measure DC voltages up to approximately 25V, making it useful for battery monitoring, power supply measurement, solar projects, and other voltage sensing applications.

The module uses a resistor voltage divider to reduce the input voltage to a lower level suitable for connection with a microcontroller's analog input. This allows compatible development boards to monitor voltages higher than their normal ADC input range.

The 25V Voltage Detection Sensor Module is commonly used with Arduino and other microcontroller platforms for measuring battery voltage, monitoring external power supplies, and developing voltage sensing systems.

Product Technical Information

Technical Details

The Voltage Detection Sensor Module 25V is a simple and useful module designed for measuring higher DC voltages with a compatible microcontroller. It is commonly used in Arduino and embedded electronics projects where the voltage being measured is greater than the direct analog input range of the controller.

The module works using a resistor voltage divider circuit. The input voltage is scaled down before being sent to the analog output pin. In a typical 25V voltage sensor module with a 5:1 voltage division ratio, an input voltage of 25V is reduced to approximately 5V at the output.

This allows compatible microcontrollers to read the scaled analog voltage through an ADC pin. The original input voltage can then be calculated in software based on the module's voltage division ratio and ADC reference voltage.

Key Features

  • Measures and monitors DC voltage
  • Maximum input voltage up to approximately 25V DC
  • Analog voltage output
  • Uses a resistor voltage divider circuit
  • Typically provides a 5:1 voltage division ratio
  • Compact and easy-to-use module
  • Suitable for microcontroller-based projects
  • Useful for battery voltage monitoring
  • Ideal for power supply measurement
  • Suitable for DIY electronics and embedded systems

Applications

  • Battery voltage monitoring
  • DC power supply measurement
  • Arduino voltage sensing projects
  • ESP32 voltage monitoring
  • STM32 embedded projects
  • Solar power monitoring
  • Robotics projects
  • Portable electronics
  • Power management systems
  • DIY electronics experiments

How It Works

The voltage sensor module reduces the input voltage using a resistor divider network. The microcontroller reads the lower analog voltage and calculates the original input voltage.

For example, with a typical 5:1 voltage divider ratio:

Input Voltage = Analog Output Voltage × 5

The exact calculation depends on the ADC reference voltage, ADC resolution, module design, and calibration.

Important Notes

  • This module is intended for DC voltage measurement within its supported range.
  • Do not exceed the maximum input voltage rating.
  • The output voltage must remain within the safe analog input range of your microcontroller.
  • ESP32 and other 3.3V microcontrollers may require additional consideration because their ADC input voltage limits differ from 5V Arduino boards.
  • Actual resistor values and module specifications may vary by manufacturer or production batch.
