Traditionally electrical appliances in a home are controlled via switches that regulates the electricity to the devices. As the world gets more and more technologically advanced, we find new technology coming deeper and deeper into our personal lives even at home. Internet of Things (IoT) conceptualizes the idea of remotely conecting and monitoring real world objects (things) through the Internet. When it comes to our house, this concept can be aptly incorporated to make it smarter, safer and automated. This Advance IoT based home automation paper focuses on building a smart wireless home automation system, in which home appliances can be accessed using mobile app/website through internet connectivity. This system can sends alerts to the owner by using Internet in case of any trespass and raises an alarm optionally. Besides, the same can also be utilized for home automation by making use of the same set of sensors. The advantage obtained by preferring this system over the similar kinds of existing systems is that the alerts and the status sent by the Wi-Fi connected microcontroller managed system can be received by the user on his phone from any distance irrespective of whether his mobile phone is connected to the internet. Apart from these features, this system also allows to check the appliance history and has many more features like recursive mode in home appliance. The microcontroller used in the current prototype is the At-mega 2560 (Arduino Mega board) with an external Wi-Fi Card ESP8266 making use of which all the electrical appliances inside the home can be controlled and managed.
