IOT BASED HOME AUTOMATION SYSTEM WITH WIFI ON ARDUINO USING ANDROID APPLICATION
The Internet of things (IoT) is a system of interconnected devices such as mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human to human or human to computer interaction. This paper consists of the proposed system with two main components; the first part is the server (web server) which presents system core that manages, controls, and monitors users' home. Users and system administrator can remotely (internet) or using Wi Fi to manage and control system code. Second part is hardware interface module, which provides appropriate interface to sensors and actuator of home automation system. The proposed system is based on Wi Fi networking technology and uses Arduino based board has its controller. The system utilization relies upon the Arduino microcontroller along with Wi Fi and hence it can be accessed with Smartphone which uses Android OS. The graphical user interface is an Android application which shows the sensors data as well as used to control the automated devices. Most of the available home automation system in the market uses Raspberry Pi and it costs higher than Arduino UNO which is scalable and flexible to manage many hardware interface modules as long as it exists on Wi Fi network coverage. The proposed system is better for scalability and flexibility with a wide range of home automation devices like power management components, and security components.
