Stand-alone device for IoT applications

Internet of Things (IoT) is a digital world of connected and talking devices, providing room for countless and diverse smart applications. This paper proposes one such IoT enabled stand-alone device with numerous capabilities: (i) interaction with user, (ii) required application selection, (iii) data sensing, (iv) data publish, and (v) decision making and actuation. The algorithm allows user to pick an application and input specific data for calibration, which on completion enables the device for further working. To verify and test its capability, a smart home garden environment is created using this device, temperature, humidity, soil moisture sensors and actuators. As it is implicit that real-time communication is inevitable for an IoT application, the sensor data is published to a Mosquitto MQTT broker to permit real-time remote access. The decision taken by the device is sent to actuators via relay, thus a continuous monitoring process is achieved. Results are obtained for the application which proves the device suitability for IoT applications.
