This document describes a project to develop a wireless dish ordering system for hotels using a touch panel and Zigbee technology. The system uses an AT89S52 microcontroller interfaced with a touch panel and Zigbee wireless modules. It allows customers to order dishes directly from their table via the touch panel, eliminating the need to manually take and deliver orders. This reduces labor costs and improves efficiency for the hotel. The system is programmed in embedded C using RIDE and the code is burned onto the microcontroller with ISP.

DESCRIPTION:
The present project deals wireless technology in the hotel management area. The
present system working is very tedious process ordering to one person sending that
with another person to kitchen sending the same to the cashier. this total procedure
will be wind up by using this project. By using zigbee technology we can reduce the man
power in the hotels and also it reduces the wastage time.
The system uses a compact circuitry built around Flash version of AT89S52
microcontroller with a non-volatile memory capable of retaining the password data for
over ten years. Programs are developed in embedded C. ISP is used to dump the code
into the microcontroller
SOFTWARE:
Embedded ‘C’
RIDE to write code
ISP to burn the chip
HARDWARE:
At89s52 based our own developed board
Power Supply
Zigbee Module
Touch panel
ADVANTAGES: Low cost, automated operation, Low Power consumption.
