Abstract:
The present project deals wireless technology in the hotel
management area. The present system working is very tedious process by
touch to control devices smoothly.
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; by select the appliance
from menu list display in touch pad, select one appliance then enter to
transmit appliance ON/OFF data to the server point.
In receiver section receive the command from respective transmitter
and selected device can operate device ON/OFF based on command. In this
way we can protect from short circuit, smooth operate device.
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.
