PASSWORD BASED CIRCUIT

 



                                      

                    Electrical linemen play a crucial role in maintaining and repairing power

distribution systems. Nowadays, electrical accidents to the line man are

increasing, while repairing the electrical lines due to the lack of

communication between the electrical substation and maintenance

staff. The password-based circuit breaker system is designed to provide

an additional layer of protection by restricting unauthorized access to

electrical circuits.This project incorporates a 4*3 keypad panel equipped

with a password input mechanism and a ESP 32 microcontroller-based

circuit breaker unit. The linemen must enter a valid password on the

keypad to activate or deactivate the circuit breaker. If the password is

valid, the relay would be switched ON while when the password is

invalid , buzzer would be alarmed and an alert message is displayed on

LCD.
