What you need

• Arduino Uno
• Connection cable
• Energy logging

Steps

1. Connect the SCT013-005 sensor to an electrical circuit to monitor.
2. Connect the sensor output to an analog pin on the Arduino.
3. Write and upload the Arduino sketch to read the sensor values.
4. Display the current values in a monitoring software like Serial Monitor.
5. Check the sensor operation with a variable load.
6. Calibrate the sensor if necessary (check the datasheet).
7. Use the collected data to create graphs or monitoring energy reports.
8. Implement additional features such as an overload alarm (check the datasheet).

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int sensorValue = analogRead(A0);
  float voltage = sensorValue * (5.0 / 1023.0);
  float current = voltage * 5.0; // Verifica sul datasheet
  Serial.print("Corrente: ");
  Serial.println(current);
  delay(1000);
}
