Residential Security Device using GSM

-

Abstract:

          Today security is most important thing in every place like homes and industries etc. So we need an automatic security system without any intention of men. 


          This project “Residential Security Device using GSM” is one of the methods to restrict theft in homes. In our project we are using PIR sensors with controllers and GSM Modem. The PIR sensors and GSM modem are fixed at the home.

          If thief enters at our home suddenly the buzzer produces the beep and the lamp will glow with the use of the controller. By the use of GSM a message is send to all of the members of the family. This system also produces electric shock at the locker when the thief touches the locker.

Operation: 



          In this project micro controller interfaced with LCD Display, GSM Mobile, External Memory, Key Board, GSM Mobile, Buzzer, Relay with driver.

         Any person entered the house PIR sensor sense person and signal send to controller. GSM mobile send the SMS to the house owner. In case of thief enters at our home suddenly the buzzer produces the beep and the lamp will glow with the use of the controller.

          By the use of GSM a message is send to all of the members of the family. This system also produces electric shock at the locker when the thief touches the locker. 

          LCD Display is used to display the SMS sending and receiving end numbers. We can also change the modes of this device and keyboard is used for setting the phone numbers to the memory.

Materials Required:


  • Micro controller      
  • LCD Display     
  • Keyboard    
  • Memory    
  • Relay with driver      
  • Alarm       
  • Calling bell       
  • Speaker
