X2 25v Voltage Sensor Module Hobby Electronics
Arduino Raspberry Pi Robot.
 
Product Details
This module is based on principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller.

This module 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)

This module 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
Parameters
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 : positive with VCC, negative with 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); 
}
