Advanced Security Guard with PIR Sensor for Commercial and Residential use

Abstract

Automation and Security have become prime concerns in our everyday life. There is a standardized approach to automation of home and industrial equipment these days. We worked on this project with two major goals, that is, to (A) provide security to shops, residential areas, factories, banks and many other places of importance which it to be guarded from theft and (B) to cover all the area meant for protection and not to restrict the view to any single area of entrance. Through this paper, we have attempted to revamp these standards by fusing new techniques for design. Here, we have integrated a cost-efficient automated security system for domestic and industrial purposes. Highest levels of security are always desirable to everyone. The designs of hardware circuit allows each user to deploy this home security system on wireless connectivity using Gas sensor, PIR sensor, Main fuse Failure Detector and Smoke sensor at houses & industries. The system is 100% controlled by the 8-bits P89V51RD2 microcontroller. Each detector and sensor is interconnected with the microcontroller chip with the help of different types of interface circuits. The microcontroller chip will incessantly supervise every sensor. In case the microcontroller senses any type of security problem, then it will send an SMS message to the registered user mobile that uses GSM modem. Microcontroller circuit also switches ON and OFF the electrical appliances at houses and industries based on SMS messages received from the GSM modem of the user.
