WIRELESS FINGERPRINT ACCESS CONTROL SYSTEM BASED ON ZIGBEE TECHNOLOGY
The purpose of this project is to operate the remote electrical appliances using fingerprint touch for domestic and industrial applications. Security is a major concern for industry or a firm. Recognizing the need for security in all the appliances we developed a fully automated security access system. Using finger print sensor module.
The sensor used here is a solid state fingerprint sensor that reliably captures finger print information. It is designed to integrate into devises for improved security and convenience. The sensor provides reliable quick and user friendly alternative to passwords and other forms of user authentication.
Zigbee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks. Zigbee is the set of specs built around the IEEE 802.15.4 wireless protocol. As Zigbee is the upcoming technology in wireless field, we had tried to demonstrate its way of functionality and various aspects like kinds, advantages and disadvantages using a small application of controlling the any kind of electronic devices and machines. The Zigbee technology is broadly adopted for bulk and fast data transmission over a dedicated channel.
We make use of this device to construct an automatic security access control system the decision like opening or closing of the door taken by an onboard computer to which the fingerprint module is interfaced.
The controlling device of the whole system is a Microcontroller. This system consists of a Microcontroller in the centralized system to which finger print sensor module. Zigbee are interfaced input and output port of the microcontroller is interfaced with different input and output modules depending on the requirements. In other words, microcontroller is a communication medium for all modules involved in the project. To perform this task the Microcontroller is programmed using Embedded C language.
This project provides us with the learning’s on the following aspects:
1. Finger print module.
2. Interfacing finger print with Microcontroller.
