This document proposes an embedded web server application for home automation and monitoring. The existing PC-based system requires servers to be on at all times, increasing costs. The proposed system overcomes this by using a PIC microcontroller connected to sensors via an Ethernet converter to directly transmit home parameters like temperature, humidity, and motion to the main server. This allows remote home monitoring through the internet without high power or hardware costs.

1. EMBEDDED WEB SERVER APPLICATION BASED
AUTOMATION AND MONITORING SYSTEM
Abstract:
As the world gets more and more technologically advanced, we find new technology
coming in deeper and deeper into our personal lives even at home. Home automation is
becoming more and more popular around the world and is becoming a common practice. The
process of home automation works by making everything in the house automatically controlled
using technology to control and do the jobs that we would normally do manually. Web enabled
systems offer great promise to education and science, businesses and consumers. A web server is
a system which hosts a web site and provides services for any requesting clients. The general
purpose web servers compose of an operating system, the web pages or the application and a
huge amount of memory and sometimes a special hardware.
Existing system:
At present PC Based web server is established at homes to monitor and automate homes.
As a result, it becomes necessary to keep the servers on all the time, which ultimately increases
the producing cost.
Proposed system:
In the proposed system, the disadvantage of the existing system is overcome by Ethernet
based web server. The home parameters such as temperature, PIR and humidity are measured
using PIC microcontroller and the values are transmitted through the Ethernet converter directly
to the main server. PIR sensor is used to monitor human activity at homes, temperature and
humidity sensors are used to measure the respective parameters. The user can monitor his home
status remotely through Internet.
