Abstract: 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 doctor sending the same to the nurse. This total procedure will be build up by using embedded system with wireless technology. By using zigbee technology we can control the device wireless. Here we developed one touch technology, it is very useful in hospitals by touch particular mention place of the nurse/attainder call in touch pad, touch specified place then enter to transmit data to the server point. In receiver section receive the command from respective transmitter and display the room number and voice announced through voice play back kit. In this way we can monitor save, patient wirelessly. The system uses a compact circuitry built around Flash version of Atmel 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

Abstract:
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 doctor
sending the same to the nurse.
This total procedure will be build up by using embedded system with
wireless technology. By using zigbee technology we can control the device
wireless.
Here we developed one touch technology, it is very useful in hospitals
by touch particular mention place of the nurse/attainder call in touch pad,
touch specified place then enter to transmit data to the server point.
In receiver section receive the command from respective transmitter
and display the room number and voice announced through voice play back
kit. In this way we can monitor save, patient wirelessly.
The system uses a compact circuitry built around Flash version of
Atmel 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
This project uses regulated 5v, 750ma power supply. 7805 three
terminal voltage regulator is used for voltage regulation. Bridge type full
wave rectifier is used to rectify the ac output of secondary of 230/18v step
down transformer.
