We are going to make WIRELESS DATA TRANSFER USING PIC(Peripheral Interface Controller) Microcontroller.The PIC18F4620 is a product of microchip. It is 8-bit controller and specially designed for ultra-low-power applications. A flexible clocking system multiple operating modes and Brown-Out Reset (BOR) are implemented to reduce power consumption and dramatically extend battery life. The data will be transmitted and received by using ZigBee transceiver module (MRF24J40MA).It is 2.4 GHz IEEE Std. 802.15.4�RF Transceiver Module .The input will be given from transmitter side by Three sets of switches and each set contains three push button switches .And the output(Graph) at the receiver side will be displayed on computer. The results can be Analyses and processed by Visual Basic .NET software etc. This device can be applicable for the following applications:

Introduction
Aim:
The aim of the project is WIRELESS DATA TRANSFER USING PIC. It builds the wireless communication system, which will help transmitting data without any mesh of wires.
We are going to built device for receiving wireless public pole. It is also useful for EVM (Electronic Voting Machine), Quiz contest etc. The input will be given from transmitter side from three sets of switches and each set contains three push button switches (A, B, C) to the slave PIC microcontroller. The microcontroller is serially communicated with the ZigBee transceiver module. The transmitted data is received at receiver side by ZigBee transceiver. And the received data is given to master PIC by serial communication. The output will be displayed on computer.
Design Specification:
- One master controller (PIC18F4620) and one slave controller (PIC18F4620)
- Two ZIGBEE trans receiver module (MRF24J40MA)
- 1 sets of switches, contents 4 switches
- Computer for out put display.
Use of Software List:
- MPLAB IDE V8.53 Compiler (Microchip Technology Inc)(free software for students from Micro Chip)
- PicPgm �For programming PIC18f Hex file load into the Chip
- Hyper Terminal Window XP Utility(Serial RS232 Interface)
- Eagle layout Editor 6.0.1(if we want to designe PCB(Printed Circuit Board))
- Proteus 7 Professional for Simulation and testing
Use of Hardeware List:

Suggestion For Further Advancement
- Here it is only a one Transmitter module but as per requirements it is compatible with more than one transmitter module.
- If LCD display is placed on each transmitter and receiver module. The transmitted question will be displayed on each student�s module and the answer will be displayed on Examiner�s module. It is possible because ZigBee is a trans receiver module.
Application Area Of Project
- Reviewing Public Pole
- EVM [Electronic Voting Machine]
- Quiz Contest
Conclusion
In today�s world use of Wireless Data Transfer becomes primary demand for the industrial application. The efficient transmitter and receiver unit with high processing capabilities for both the modules which can process the received information give optimization result has become necessity.
Keeping these things in mind we have come up with an idea to transmit and receive data wireless using ZigBee and PIC controller which mostly suffices the above requirement. The result has been shown and verified.
