This book presents the development of a low cost embedded wireless smart home prototype system for controlling home appliances in a building. The system provides a friendly user interface Android application based smartphone for controlling appliances and devices from anywhere in the world with an IP connectivity for accessing the embedded micro web-server. This system uses an Arduino Ethernet interface which runs a simple data web server to avoid using a personal computer as a server to keep the overall system cost to minimum. For the communication between the micro web-server node and the end nodes, XBee modules are used. What makes ZigBee stand apart from the rest is the easy to use, extremely low power consumption, cost effective, reliability, low latency, supporting a huge number of connected nodes into a single control network.
