    Description:

    • 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.

    Parameter:

    • 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 toGND

    • Output interface:

    • "+" is 5 / 3.3V,

    • "-" then GND,

    • "s" A rduino connected to the AD pin

    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); 

    }
