Home Automation System with Remote Access through Web Server

Abstract

In our homes, we have to control our appliances for our comfort. As most of the controlling are done manually, a lot of power is wasted every day if sometimes we forget to switch-off any appliance, which is a very common phenomenon. If we control home appliances through a remote access, then we can easily abrogate the problem. We have designed a system where appliances can be controlled through a web server. This system is also helpful for people who are physically disabled, as the system can be accessed through cell phone or computer connected to the internet. The proposed system has three sub-systems, i.e. (1) hardware for appliance control, (2) interface between hardware and web server and (3) web based server.We are using Arduino in the hardware level to control appliances. To work as an interface between the server and Arduino, we have developed an application in Python programming language. The web server serves up a website; we used PHP programming language to design this website through which we can control and also show the on/ off status of home appliances. The appliances are connected with an Arduino board and the Arduino board is connected with a local server (i.e. pc). The local server is communicating with the web server through internet. Through the server, a client gets the authority to monitor and control the on/ off states of the appliances. In order to ensure the security of the system, we have implemented password protection for the clients on the website.
