DC Voltage Sensor Test tegangan 0V to 25V Detection Module for Arduino

Description:



Voltage input range: DC0-25V

Voltage detection range: DC0.02445V-25V

Voltage Analog Resolution: 0.00489V

DC input connector: Terminal cathode connected to VCC, GND negative pole

Output interface: "+" then 5/3.3V, "-" then GND, "s" then the Arduino AD pins



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);
