Zigbee Wireless Sensor Network for Smarthome

Abstract

This thesis implements a wireless sensor network based on ZigBee technology for smarthome system. The network includes six nodes with one coordinator, two routers and three end devices. Each node includes PIC microcontrollers and Microchip RF modules. This network collects the temperature and controls the devices in house. In end device node, PIC chip collects the temperature from the sensor and send to the coordinator node for monitoring function. The coordinator node can send commands to control the devices connected with another end device node, for example lights, fans... Another end devices node acts as remote control connected with the coordinator can also control the devices in network. The routers are used for extending the range of the network. In this thesis, I also plan to place the nodes in different places of the building for testing data transmitting and receiving function of ZigBee nodes, and also testing the routing function of Zigbee nodes in network..
