Ethernet Enabled Digital Home Automation System

Abstract

This paper presents very intelligible and economical method to provide Ethernet connectivity to microcontroller based controlled embedded systems. This system uses TCP/IP stack as a very essential element of the system software and also uses ATmega328p as a host microcontroller to store the main application source code, web pages. An Ethernet controller chip, ENC 28J60 is used to handle the Ethernet communications which is interfaced with the host microcontroller using SPI pins. There are many I/O pins available at the microcontroller which is used to interface with relays for controlling operations remotely. Nowadays, most of the internet connections use Ethernet as media for data transfer. Most of the time we need to control different home appliances using microcontrollers. If we enable Ethernet interface to such systems then we can communicate with them remotely over the internet with wired by means of wired or wirelessly.
