RF Based Hotel Ordering Menu Card System Projects
In today’s world number of restaurants is increasing. They
also require very fast processing for serving food to the customers.
Many times in hotel we have to wait for a waiter to give our order for food.
This creates problem when there is rush in hotel especially in festival seasons
and generally on weekends. With the increasing number of customers, it
would require more man power, since the current situation has become
hectic for the restaurants. Also changes in the hardcopy of the menu can’t
happen
n order to solve these
problem, here we had design a simple automation system called RF based
hotel ordering menu card system which consists of a transmitter and
a receiver section this system provides wireless
communication using an electronic menu card
provided on each table. We can select the items through matrix keypad provided. This order
details are collected by wireless
receiver placed in the kitchen and will display the items in its display.
So the kitchen people can supply those items to the customer after preparing it.

in this project Transmitter section is used for ordering from the menu. An electronic card is provided on each table. 8051 Microcontroller displays the food items on the LCD screen with their prices. The customer can select the items and send the items order by using key. Microcontroller then reads data from the keypad and gives corresponding digital output to an encoder. It encodes one of the active inputs to a coded binary output. RF transmitter transmits this coded binary output from the encoder.
At The receiver section is placed in the
kitchen, it consists of an RF receiver. RF receiver receives the coded binary
data transmitted by the RF transmitter and given to the RF decoder. RF decoder
decodes the input and gives four bit digital data to the PC only if the address
bit of encoder and decoder matches. Software is installed in computer to
display the selected items.
The RF module operates
at Radio Frequency and signals through RF can travel through larger distances making
it suitable for long range applications and the RF signals can travel even when
there is an obstruction between transmitter & receiver.
