    Two-way Wireless Data Messaging System for Rural Areas using Zigbee Technology

    Two-way Wireless Data Messaging System for Rural Areas using Zigbee Technology
    Title of the project: Two-way Wireless Data Messaging System for Rural Areas using Zigbee Technology
    Domain: Wireless Embedded Systems Design
    Software: Embedded C, Keil, Proload
    Microcontroller: AT89S52
    Power Supply: +5V, 500mA Regulated Power Supply
    Transmitter Display: LED 5mm, 16 X 2 LCD
    Receiver Display: LED 5mm, 16 X 2 LCD
    Input Source: Key Pad
    Crystal: 11.0592MHz
    Communication Device: Zigbee Module
    Applications: Wireless Communication



    ABSTRACT

    In this project, the data can be transmitted to and received from remote ZigBee communication device. Data Security is primary concern for every communication system. There are many ways to provide security data that is being communicated. However, what if the security is assured irrespective of the hackers are from the noise. This Project describes a design of effective security for data communication by designing standard algorithm for encryption and decryption.
    Zigbee is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, ZigBee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area. The source information is generated by a key pad and this will be encrypted and is sent to destination through Zigbee modules. The receiving system will check the data and decrypt according to a specific algorithm and displays on the LCD.
    This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
