Now a day’s technology becomes ever additional invasive, the look challenges in home automation area unit progressively apparent. Seamless dominant home, observation and programming by the tip user have nonetheless to enter the thought. This might be legitimate to the challenge of developing a completely freelance and protractile home system that may support devices and technologies of differing functionalities and protocols. 
This paper describes how to control and monitor home appliances using android application over internet. There are number of commercial home automation systems available in market. However, these are designed for limited use. Therefore, home appliances can individually be controlled both from within the home and remotely. This is very helpful to physically challenged people. 
The practical goal of this paper has been to create a virtual, but practically usable, android home automation system. The humanoid mobile is employed to send the commands to the Arduino to manage all the house appliances. And another feature is we have a tendency to could get the standing of our home appliances from our humanoid portable. The main feature of this system is to control the voltage levels of home appliance in home like speed of fan based on temperature, intensity of light based on light intensity etc. In this system we use different sensors like temperature, rain sensor and LDR for different applications.
