With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.

PROJECT DESCRIPTION

The main objective of this project is to provide a security system with a provision to change the password by an authorized person only. This proposed system provides a user-friendly security system for organizations and homes. This system is password based and allows only authorized person to access it with the password.

The system is fully controlled by an 8-bit microcontroller of the 8051 family. A password is stored in an EEPROM interfaced to the microcontroller which is possible to be changed anytime unlike a fixed password burnt permanently to the microcontroller.

A keypad is used to enter the password and a relay is interfaced to the microcontroller using a relay driver to lock or unlock the electric door, which is indicated by the lamp in the project. Any wrong attempt to open the door (by entering a wrong password) prompts an alert indicated by another lamp.

Furthermore, this project can be enhanced by interfacing a GSM modem to the device so that when a wrong password is entered, an alert SMS will be sent to the concerned authority.
