1. DC of the microcontroller it is continuously being checked for any signal So as soon as there is motion detection through this motion sensor the microcontroller sends a signal to the ZigBee module through UART After getting a signal for motion sensor the ZigBee module tries to find a ZigBee tag in the person s hand If the ID given by the Tag is correct it will ask for secret code if it matches with the previous stored code then the microcontroller will move the motor to open the door otherwise it will run the buzzer Even if there is no ZigBee tag in the persons hand it will run the buzzer The door will close after a delay automatically B Direct Message In this mode of working the ID is send before the person is being detected through the motion sensor This can be accomplished through the use of the switch of the ZigBee module which is being used as the tag As soon as the ID reaches the ZigBee module in the digital door lock module it will send the ID to the microcontroller which will compare it with the stored tag ID If the Tag matches with the stored ID then it ask for secret code after that again it will match the code with the stored ones if correct then it will move the motor to open the door otherwise it will run the buzzer The door will close automatically after a delay C Tag Registration Password Registration This mode starts only when the switch for registration in the ZigBee module present in the digital door lock module is press

IJIRST International Journal for Innovative Research in Science amp Technology Volume 2 Issue 01 June 2015 ISSN online 2349 6010 Automated Security System using ZigBee Sneha Susan Abraham Saveetha School Of Engineering Saveetha University Abstract Nowadays Wireless Security Monitoring System is one major research topic in field of Intelligent Buildings In this paper we present a Wireless Home Security System Using ZigBee Rather than using the traditional method to implement the real time surveillance of the home security the system was developed using ZigBee for the wireless connectivity The system can set the alarm Open the Door and Close the Door The Hardware and Software and working of the system are explained in detail A number surveillance device can be connected for further improvement of the system Keywords Wireless Security System ZigBee Module Digital Door Lock Human Detection Module ZigBee Relay Module Motion Sensor I INTRODUCTION Home Security System is a system used to protect our home from intruders theft i e system used to keep our home safe amp secure There are two methods for home networking system 1 Conventional method 1 e wired 11 Un conventional method i e wirelesses Compared to wired system wireless system provides more flexibility extensibility and is free from construction works In this system design the wireless technology which is used is ZigBee This is an electronic lockin
3. Total setup for the system VII RESULTS AND FUTURE WORK This paper is concerned about designing an access monitoring and control system using ZigBee The network between the two ZigBee were established succefully The modules were communicating properly and successfully The full system was working properly This system is more advantageous than other methods because low power consumption which is achieved by the use of ZigBee module Since ZigBee is having low power consumption as well low data rate this system will consume low power This system is limited only to the access control and monitoring This can be extended to make a full home security system in which we can attach various sensors like temperature sensor humidity sensor smoke sensors to protect our home from hazards like fire and to control the various devices in home like light fan A C or devices according to the requirement In this camera facility can be provided to improve the security and to facilitate the user to interact with the outsider if they don t have the Tag All rights reserved by www ijirst org 299 1 2 3 4 5 6 7 8 9 Automated Security System using ZigBee IJIRST Volume 2 Issue O1 042 REFERENCES K Hwang and J W Baek Wireless Access Monitoring and Control System based on Digital Door Lock IEEE Transactions on Consumer Electronics vol 53 no 54 Nov 2007 A Wheeler Commercial Application of Wireless Se
