SMART HOME USING INTERNET OF THINGS(IoT)
Keywords:
Arduino Mega, MQTT, IoT, Ethernet shield, (M2M) technology.Abstract
This paper provides an overview of the Internet of Things (IoT) with emphasis on enabling technologies,
protocols, and application issues. The IoT is enabled by the latest developments in RFID, smart sensors, communication
technologies, and Internet protocols. The basic premise is to have smart sensors collaborate directly without human
involvement to deliver a new class of applications. The current revolution in Internet, mobile, and machine-to-machine
(M2M) 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.
