As we know that in today’s world wireless technology is become a
passion in each industry, because of its positive outputs as well as the
atomization, compactness.
Our project “E- HOTELLING “is one step towards the wireless atomization
in hotel industry. Which deals with the placing the order in atomization form
without a manual efforts.
The
microcontroller based embedded system proposed under is an alternate solution
for the above problem along with the addition to your hotel atomization. The
system called E -Hoteling serves a menu card to the customer along with the
rates on the LCD display. The customer can place his order by selecting the
food by means of keypad provided. The order placed will then be transmitted
directly to the kitchen and displayed on the LCD mounted at the kitchen along
with the table no.
We are
developing this embedded kit basically for the standard restaurants where the
customers are in the position to handle the kit in the user friendly manner.

WORKING
In this
project we have a kit containing LCD display and Keypad which is positioned on
each table in a hotel. When customers want to choose his menu then he has to
just press the “reset” key as soon as he reset the key the whole menu card with
prices, after that he has to select the required option after selected the item
he has to press the “enter” key. After that the whole data will be transferred
serially in the form of data pattern through RF transmitter for this purpose we
use the “Amplitude Shift Keying Modulation (ASK)” is used.
After sending
the data the receiver will receive that data stream after receiving this
microcontroller will send the data to the LCD display. After getting this
message the cook will place this order to particular table.
