Home Appliences Control By Using Zigbee Module

In this project we transmit digital data through radio frequency modulation system, transmitting, receiving purpose zigbee transmitter and receiver is use. So this project has two sections. One is transmitter in which switches, micro-controller unit, and regulated power supply and zigbee transmitters. And second are receivers in which zigbee receiver, micro-controller unit, and relay are the main blocks. There are various types of transmitter and receiver, present in market. But zigbee transmitter is the latest technology. This transmitter can transmit direct digital data at 2.4GHz international standard range in mode. This Transmitter has 4 pins Vcc, Data in and Antennae. This is again latest technology receiver which cans response only zigbee signal and rejects all type of noise present in the Input. This receiver has four pins viz. +Vcc, ground & data out and antenna. The output of this receiver is in digital pulse form, which is transmitted by transmitter, which is connected to pin of micro-controller in receiver section. This.transmitter and receiver is operated at 2400 baud rates and 20 meter range.
