Circuit Breaker Based On Password
Project Idea:
This project is designed to enhance safety for electrical line workers by allowing them to directly control the electrical circuit through a password-based system. It prevents accidents caused by miscommunication between linemen and substation staff during maintenance work. The circuit can only be turned ON/OFF by entering the correct password on a matrix keypad, making the operation secure and manual from the lineman's side.

  • 8051 Microcontroller
  • Matrix Keypad
  • LCD Display
  • Relay Driver IC
  • Voltage Regulator IC
  • EEPROM IC (for password storage/upgrade)
  • Resistors, Capacitors, Transistors
  • Diodes
  • PCB and Breadboards
  • LEDs
  • Transformer/Adapter
  • Push Buttons
  • Switch
  • IC & IC Sockets
  • Cables and Connectors
  • Lamps
 
Project Features:
  • Secure password-based ON/OFF control of circuit
  • Matrix keypad input for password entry
