Standard Voltage Sensor Module

KR-SR0087

New

This module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.

  • Quantity:1pc
  • Size: 25mm×13mm/0.98"×0.51"(approx)
  • This module is based on 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 (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V). Arduino 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 Arduino AD pins
  • DC input interface : red terminal positive with VCC, negative with GND
  • By 3P connector, connect this module with the expansion of board Arduino, not only makes it easier for you to detect voltage battery, can also use the IICLCD1602 LCD to display voltage.
  • 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);
    }
