Introduction:

This module is based on a resistive divider principle design, make the interface terminal input voltage reduced 5 times, A rduino analog input voltage up to 5V, then the input voltage of the voltage detection module can not be greater than 5V × 5 = 25V (if used 3.3V system, the input voltage can not exceed 3.3Vx5 = 16.5V). Because A rduino AVR chips used in 10 AD, so the resolution of the analog module is 0.00489V (5V / 1023), so the voltage detection module detects a minimum input voltage of 0.00489V × 5 = 0.02445V.
    
    Parameters:
    Voltage input range: DC0-25V
    Voltage detection range: DC0.02445V-25V
    Voltage analog resolution: 0.00489V

    Wiring:
    DC input connector:
    
    the positive terminal connected to VCC,
    the negative  connected to GND
    Output interface:
    "+" is 5 / 3.3V,
    "-" then GND,
    "s" Arduino connected to the AD pin


    Arduino Code:

    #include


    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);
    }
