Modul senzor curent 3A MAX471

Specificatii tehnice:

Interval tensiune suportata: 3 - 36V DC
INterval curent masurat: 0-3A DC

Schema circuit a modulului:

Exemplu cod arduino:

const int max471Out = A0;

int RawValue= 0;
float Current = 0;

void setup(){
pinMode(max471Out, INPUT);
Serial.begin(9600);
}

void loop(){
RawValue = analogRead(max471Out);
Current = (RawValue * 5.0 )/ 1024.0; // scale the ADC
Serial.print("Current = "); // shows the voltage measured
Serial.print(Current,3); //3 digits after decimal point
Serial.println(" amps DC"); //3 digits after decimal point
delay(200);
}
