Electronic Circuit Breaker Project

Introduction:

A circuit breaker is an essential component in any electrical system, designed to protect the circuit from overcurrents and short circuits. Traditional circuit breakers use mechanical contacts to interrupt the circuit, but electronic circuit breakers use electronic devices to detect and interrupt the current. This project aims to design and build an electronic circuit breaker using a microcontroller and a relay.

Components:

Microcontroller (e.g. Arduino Uno)
Relay module (e.g. 5V SPDT relay)
Current sensor (e.g. ACS712 current sensor)
Voltage regulator (e.g. 5V voltage regulator)
Breadboard and jumper wires
Power supply (e.g. 9V battery or wall adapter)

Circuit Diagram:

The circuit diagram is shown below:

How it Works:

The current sensor measures the current flowing through the circuit and sends the signal to the microcontroller.
The microcontroller monitors the current signal and compares it to a set threshold value.
If the current exceeds the threshold value, the microcontroller sends a signal to the relay module to interrupt the circuit.
The relay module uses the signal to switch the circuit on or off.
The circuit breaker can be reset by pressing a button or by waiting for a set time period.

Code:

The code for this project is written in Arduino programming language and is shown below:

const int currentSensorPin = A0;  // Pin for current sensor
const int relayPin = 2;  // Pin for relay module
const int thresholdValue = 10;  // Threshold value for current

void setup() {
  pinMode(relayPin, OUTPUT);
  Serial.begin(9600);
}

void loop() {
  int currentReading = analogRead(currentSensorPin);
  float current = (currentReading * 5.0) / 1024.0;
  if (current > thresholdValue) {
    digitalWrite(relayPin, HIGH);
    Serial.println("Circuit interrupted!");
    delay(1000);
  } else {
    digitalWrite(relayPin, LOW);
  }
  delay(10);
}

Conclusion:

This electronic circuit breaker project uses a microcontroller and a relay module to detect and interrupt the current in a circuit. The project is designed to be simple and easy to build, and can be modified to suit specific requirements. The code provided is a basic example and can be modified to add more features such as hysteresis and timing.
