Voltage Detection Sensor Module 25V

Voltage Detection Sensor Module 25V

A simple but very useful module which uses a potential divider to reduce any input voltage by a factor of 5. This allows you to use the analogue input of a microcontroller to monitor voltages much higher than it capable of sensing. For example with a 0-5V analogue 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.

Specification:

  • Divider ratio: 5:1
  • Resistor Tolerance: 1%
  • Max input voltage: 25V 
  • Resistor Value: 30K/7.5K Ohm


Pinout:

  1. INPUT
    1. Pin 1 - GND
    2. Pin 2 - 0-25V
  2. OUTPUT
    1. Pin 1 - Sense
    2. Pin 2 - NC
    3. Pin 3 - GND

Reference Code:

#include <Wire.h>

int val11;
int val2;

void setup ()
  {
  pinMode (LED1, OUTPUT);
  Serial.begin (9600);
  Serial.println ("Emartee.Com");
  Serial.println ("Voltage:");
  Serial.print ("V");
 }
void loop ()
  {
  float temp;
  val11 = analogRead (1);
  temp = val11 / 4.092;
  val11 = (int) temp; //
  val2 = ((val11% 100) / 10);
  Serial.println (val2);
  delay (1000);
  }
