#1655: DC 0-25V Voltage Sensor Module (Voltmeter Arduino)


A DC 0-25V voltage sensor module is a device that measures DC voltage in the range of 0 to 25 volts. These modules are often used to measure the voltage of batteries, power supplies, or other electronic circuits.

To use a DC 0-25V voltage sensor module with an Arduino, you will need to connect the module to the Arduino and write a sketch to read the voltage measurement. The module will typically have three pins: a power pin, a ground pin, and a signal pin. The power pin should be connected to the power source being measured, and the ground pin should be connected to the ground of the power source. The signal pin should be connected to an analog input pin on the Arduino.



  • This module is based on principle of resistive voltage divider design,
  • can make the red terminal connector input voltage to 5 times smaller. input voltages up to 5v,
  • the voltage detection module input voltage not greater than 5Vx5=25V
  • (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V)
  •  AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),
  • so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.
  • Voltage input range : DC0-25 V
  • Voltage detection range : DC0.02445 V-25 V
  • Voltage analog resolution : 0.00489 V
  • Output Interface : "+ " connected 5/3.3V, "-" connected GND, "s" connected AD pins
  • DC input interface : red terminal positive with VCC, negative with GND
  • By 3P connector, connect this module with the expansion of board,
  • not only makes it easier for you to detect voltage battery,
  • can also use the IICLCD1602 LCD to display voltage.
