    Product Description


    Voltage Sensor module for Arduino and others

    Voltage Sensor module for Arduino and others

    Module introduction:
    This module is designed based on the principle of resistor divider, which can reduce the voltage of the terminal interface input by 5 times. The Arduino analog input voltage is up to 5V. The input voltage of the voltage detection module cannot exceed 5V×5=25V (if 3.3V is used) System, input voltage can not be greater than 3.3Vx5=16.5V). Because the AVR chip used by Arduino is 10-bit AD, the analog resolution of this module is 0.00489V (5V/1023), so the minimum voltage detected by the voltage detection module is 0.00489V×5=0.02445V.
    Parameters:
    Voltage input range: DC0-25V
    Voltage detection range: DC0.02445V-25V
    Voltage analog resolution: 0.00489V
    DC input interface: Connect positive terminal to VCC and negative terminal to GND
    Output interface: "+" is connected to 5/3.3V, "-" is connected to GND, and "s" is connected to the AD pin of Arduino
    Sample 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);
    }
