IOT Based Home Automation For World Wide Accessing

Internet of Things (IoT) links smart objects to the internet. It can enable exchange of data in a more secure way. Rapid adaptations of Smart City and Internet of Things technologies are assisting in urban planning to ensure sustainable cities and lifestyles. Life is made simpler and more productive through IOT. As the Wi-Fi hotspots are increasingly becoming common in the recent times, the existing infrastructure can be used to develop a cost effective solution to enable the existing appliances with IOT. In the existing system, the home appliances are controlled through Bluetooth, zigbee and other devices. But they are limited to certain area. In the proposed system we have designed so as to control home appliances from anywhere in the world.
In the proposed system, we are using Nodemcu Wi-Fi module. We will create a separate host server for the Wi-Fi Module to control the Home appliances wirelessly. A User Id and Password is also created to the User to login in to the Host Server. Using an IP address we can get associated with the nodemcu module and we can send input signals to the corresponding load which will get activated through relay. The user can have access to operate the loads from anywhere in the world.
