Advanced Menu Ordering System in Restaurants

Smart Restaurant is a concept of automation of menu ordering system in hotels and restaurants. Instead of a person has to attend manually and enter the order placed in each table, the proposed system brings an ordering system with electronic menu. With this type of restaurant, the kitchen people can obtain orders from each table wirelessly. This system comprises of a transmitter section at customer table and receiver section at kitchen table.  In this design an electronic system collects orders from each table with electronic menu card and transmits through wireless communication. Using a matrix keypad the items to be ordered can be selected. These ordered details are received by a wireless receiver in the restaurant kitchen and items list is displayed in a display unit so that the people in the kitchen can supply those ordered items after preparing them.  Thus the time delay experienced by the customer usually during arrival of bearer to collect the order and pass to the kitchen is reduced drastically. The system is built using PIC16F877 microcontroller, Liquid crystal display and 2.4 GHz open band wireless transceiver modules for communication. The whole system can be operated within a range of 30m indoor.
