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.
