Door monitoring system using zigbee networks

Abstract

The topic of this thesis is “Door/Window Monitoring System Using Zigbee Network”. The goal of this thesis is to use the Zigbee MRF24J40MA, WPAN 802.15.4 protocol, to transmit and display the status (open or close) of the doors or windows (end-device) in the IU building to the computer (coordinator). The thesis is divided into two parts; the first part is the development “Zigbee Network” and the second part is the development of the “Sensor Display” to display the door’s and window’s status. In the first part, we create a Zigbee network system to include four nodes: one coordinator (computer), one router and two end-devices (door or window). The status of the door or the window will be transmitted to router. The router will retransmit the status of the door to the coordinator. In the second part, we create a Sensor Display by using Visual Basic 6 for communication interface and Hypertext Preprocessor (PHP) programming language for the display. This sensor display program will receive the door’s and window’s statuses of all seven floors of the International University from the Zigbee network and display them on the web graphic interface.
