Good morning.
I am trying to measure the power of an electrical device. I use an SCT013 with a SEN0211 ( https://www.tme.com/us/es/details/df-sen0211/otros-sensores/dfrobot/sen0211/ )
I copied an example and tried it. It doesn't measure correctly. The truth is that I don't really know what I'm doing. Does anyone know or have an example that I can follow to correctly measure the power? I'm attaching the code I'm using and it doesn't measure correctly.
I have tried it with different Arduinos, please note:
For Arduino UNO, Leonardo and mega2560, etc. change VREF to 5
For Arduino Zero, Due, MKR Family, ESP32, etc. 3V3 controllers, change VREF to 3.3
Thanks.

//Potencia
const int ACPin = A3; //set arduino signal read pin
#define ACTectionRange 20; //set Non-invasive AC Current Sensor tection range (5A,10A,20A)

// VREF: Analog reference
// For Arduino UNO, Leonardo and mega2560, etc. change VREF to 5
// For Arduino Zero, Due, MKR Family, ESP32, etc. 3V3 controllers, change VREF to 3.3
#define VREF 3.3

void setup()
{
Serial.begin(9600);
delay(1000);

Serial.println(" ");
Serial.println("-> Inici SETUP ");
Serial.println("-> Ausatel Sistemes 2023 ");

//Potencia
Serial.println("-> Fi SETUP");
}

void loop()
{

float ACCurrentValue = readACCurrentValue(); //read AC Current Value
Serial.print(ACCurrentValue/2);
Serial.println(" A");
Serial.print((ACCurrentValue/2) * 230);
Serial.println(" W");
delay(3000);
}

// Funció llegir potencia
float readACCurrentValue()
{
float ACCurrtntValue = 0;
float peakVoltage = 0;
float voltageVirtualValue = 0; //Vrms
for (int i = 0; i < 6; i++)
{
peakVoltage += analogRead(ACPin); //read peak voltage
delay(1);
}
peakVoltage = peakVoltage / 6;

voltageVirtualValue = peakVoltage * 0.707; //change the peak voltage to the Virtual Value of voltage

/*The circuit is amplified by 2 times, so it is divided by 2.*/
voltageVirtualValue = (voltageVirtualValue / 1024 * VREF ) / 2;

ACCurrtntValue = voltageVirtualValue * ACTectionRange;

Serial.print("VoltageVirtual = "); Serial.println(voltageVirtualValue);
//Serial.print("ACTectionRange = "); Serial.println(ACTectionRange);
Serial.print("ACCurrtntValue = "); Serial.println(ACCurrtntValue);
Serial.println("********************************");

return ACCurrtntValue;
}
