The main aim of the project is to design a system which can get orders from distant area using wireless technologies
The purpose of the project is to implement a wireless communication system in small hotels to take the menu order and to transmit this information to the main section. .
In this project the microcontroller which forms the heart of the project, plays an important role in establishing communication between transceivers. The microcontroller communicates with Zigbee transceiver and sends the data to the corresponding transceiver.
This project consists of two sections one is hand held device section and other is main section. Both sections consist of Zigbee transceivers. From the first section menu should taken and saved in EEPROM in that section.
This information is forwarded to the main section via Zigbee wireless communication. Main section will receive the information from the first section and stores that data in EEPROM. According to that order which is stored in memory service is provided. Here LCD is used to display the data on LCD.PC is used to display data and record for billing.
Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the wide range controlling applications and to replace the existing non-standard technologies. It currently operates in 868 MHz band at a data rate of 20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide at a maximum data-rate of 250kbps.
It is used to verify whether user's truncation is possible or not. One of the main advantages of this ZIGBEE communication is that it provides a noise free communication, the amount of noise added in this type of communication is very less compared to the other wireless communications
According to this project we can implement a wireless menu ordering systems using wireless communication.
