This project focuses on the development of a smart home system that allows users to control electrical appliances using a device such as an Android phone via Bluetooth or the internet. Home Automation using Mobile is going to be used for the control of home appliances. It enables you to control home appliances like Bulbs, fans, Televisions, etc with the pressing of your mobile key from anywhere. There is no need for a specific remote for this. The user can control any appliances with this application. So, if you forgot to switch off the lights or other appliances while going out, it helps you to turn off the appliance with your cell phone. This system adapts serial connection of the devices with a Bluetooth module and an ARDUINO microcontroller attached to the main circuit board where the microcontroller will then control the home appliances via a relay circuit. The smart home system will be able to ease the effort of physically challenged individuals in controlling their home appliances such as lamps, fans, air-con, etc... Users can trigger the switches anywhere as long as the device is within the vicinity of the Bluetooth signal in the main panel. Moreover, users can also control the appliances via an internet connection by sending an email to a specified address. With this limitation, users will have no flexibility in controlling their home appliances when they are not at home and this prevents remote monitoring of their home devices.
