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:
- PIC18F4620 Microcontroller IC (Microchip Technology Inc) – 2 Pisces
- MRF24J40MA ZigBee transceiver Modual (Microchip Technology Inc)– 2 Pisces
- General purpose PCB (GPP)
- Soldering iron,solder wire,Connector,Power Supply (SMPS ) 5Volt 2A etc.
- Push button switches

Hardware Implementation and PCB Connection:
Observation
1. Zigbee co-coordinator initialized and turning on joining
with End device.
2.After pressing key 1 and it
is displayed on hyper terminal.
3. After pressing key 2 and it is displayed on hyper
terminal.
4. After pressing key 3 and
it is displayed on hyper terminal.
5. After pressing key 4 and it is displayed on hyper
terminal.

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.
