  • This is Voltage Sensor Module 25V
  • The Voltage Sensor Module 25V is a precise low-cost sensor for measuring voltage.
  • The operating voltage of this sensor ranges from 0V - 25V.
  • This voltage sensor can be Interfaced with Arduino or any other microcontroller.
  • The Analog Voltage Resolution is 0.00489V.

Voltage Sensor Module 25V

The Voltage Sensor Module 25V is a simple but very useful module that uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Detection Sensor Module 25V allows you to use the analog input of a microcontroller to monitor voltages much higher than it capable of sensing.

For example with a 0-5V analog input range, you are able to measure a voltage up to 25V. The module also includes convenient screw terminals for easy and secure connection of a wire.

This module is based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Arduino analog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V.

1. What is a voltage sensor module?

  • A voltage sensor is a device that detects electric current in a wire and generates a signal proportional to that current. The generated signal could be an analog voltage or current, or it could be a digital output. Voltage sensors can detect both AC and DC voltage levels.

2. How many pins voltage sensor module has?

  • A 25V Voltage Sensor has 5 pins in total. Two are two-pin screw terminals, and three are male header pins. The Screw Terminal pins are labelled VCC and GND, and they must be connected to the external voltage source, i.e. the voltage to be measured.

3. Where can I use the Voltage sensor module?

  • The voltage sensor module is a 0-25 DC voltage sensing device that is based on a resistive voltage divider circuit. The voltage sensor module can be used in voltage measurement, Fault sensing, Safety switching, and Power Control

4. What is the purpose of the voltage sensor?

  • Voltage sensors are wireless devices that can be attached to a wide range of assets, machinery, and equipment. They provide round-the-clock monitoring, constantly looking for voltage data that may indicate a problem. Low voltage may indicate a problem, whereas high voltage may endanger other assets.
