In this paper, the authors design and implement the security system for shop, home or industry that can provide more secure model against intrusion. The main component used in this paper is the microcontroller AT89S52, GSM modem, sensors i.e. magnetic and PIR for detection of intruder. The microcontroller gets the signal from the sensors placed at entry side of shop, home or industry then the microcontroller gives the command to the GSM to send the SMS and make a call to the owner and also to the authorized person.
