Implementation Of Secured Room Access System Based Microcontroller

Abstract

This project is developed for the users to have security through Telephone. Usually if someone tries to open the door or shutter, the security unit produces siren. But this project is specially designed to make a call to the owner and intimates the owner that there is something strange. The main part of the Unit is Microcontroller and Magnetic sensor. When the owner closes the door or shutter, he will on the switch attached in the phone. After that if some one tries to open the door, the magnetic sensor senses and sends signal to the Microcontroller unit. The micro controller immediately handles the phone operation completely. It first handles the hook button and then flash key simultaneously for some time and then starts dialing to the particular numbers already set. If the owner and other numbers set are busy, again and again it tries to the particular numbers. When they attend the phone, the Unit tells the message through the Microphone. Thus the owner has to come and handle the situation. This unit also senses if there is any fire. If happens, it will do the same operation and tells the owner that there is fire. This project is very useful in Houses, Industries, Institutions, Shops etc where high security is needed.
