Smart Home Automation System by using Internet of Things

Internet of Things (IoT) is a concept of imagines all objects around us as part of internet. IoT includes the very wide range of objects and variety of objects like smart phones, tablets, digital cameras and sensors. In the IoT All these devices are connected to each other, they enable more smart services and processes that support our everyday needs, environment and health. The current revolution in Internet, mobile, and machine-to-machine technologies can be seen as the first phase of the IoT. Arduino Mega controller is used as a controller to control and monitor many applications through server. Status of every device is continuously monitored on webpage and user can use this data to switch the device. MQTT (message queue telemetry transport) protocol is used for communication of data. It was designed as an extremely lightweight publish/subscribe messaging transport the communication between the controller and devices is achieved by putting both the systems in the same network using Ethernet shield, mounted on the Arduino. IoT applications that use real-time sensor values to optimize business processes, improve the quality of life, or increase safety in critical environment.
