Restful Webserver Based Domotic Home Using Power over Ethernet

This paper presents the way to provide Ethernet internet connectivity and power to microcontroller based embedded systems. This system uses arduino board to store the main application source code, web pages and TCP/IP stack which is a vital element of the system software. An Ethernet controller chip, ENC28J60 is used to handle the Ethernet communications and it is interfaced with the microcontroller using SPI protocol. The site can be viewed on any system with Internet/LAN connection by configuring the specific IP address. There are several I/O pins available at the microcontrollers which are used to interface with lights, fans, curtains, Motors and relays for monitoring and controlling DC appliances. Nowadays, Internet has spread worldwide and most of the internet connections use Ethernet as media for data transfer. In industries or in home appliances, most of the time we need to monitor and control using microcontrollers. Once we enable Ethernet interface to such systems, we can communicate with them remotely over the internet. At the same time power which require to run the device is provided by using power over Ethernet technology which minimize the cable requirement and wastages of copper conductors. The concept of the "Internet of Things" has tied in closely with the popularization of home automation. Ethernet provides inexpensive, relatively high speed network access to individual users and low delay that can support many applications. This implementation is an attempt to connect an embedded device to an Ethernet Using Ethernet based system we can control various home appliances from anywhere across the world.
