Tutorial: How to use SCT013-010

The SCT013-010 is a split-core current sensor that allows measuring electrical current in a circuit without interrupting it. Ideal for energy monitoring and automation projects.

What you need

• Arduino
• 5V power supply
• test connector
• connection wires
• multimeter

Steps

1. Connect the SCT013-010 sensor to the 5V power supply and ground.
2. Check the proper connection with a multimeter.
3. Connect the sensor output to an Arduino analog pin.
4. Write an Arduino sketch to read analog values.
5. Calibrate the read values to real current (check the datasheet).
6. Display the data on an LCD or transmit it via Wi-Fi.
7. Implement an alarm or automatic control system.
8. Test the system with different electrical loads.

Example code

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

void loop() {
  int val = analogRead(A0);
  float voltage = val * (5.0 / 1023.0);
  float current = voltage * 10; // verifica sul datasheet
  Serial.print(voltage);
  Serial.print(" V, ");
  Serial.print(current);
  Serial.println(" A");
  delay(1000);
}
