Abstract: Internet of Things (IoT) applications serves several areas, in which Real Time Applications has major siginificance and are widely used. In this paper, we discuss the implementation of IoT Services such as Room Temperature Monitoring and Fire Alarm System using Message Queue Telemetry Transportation (MQTT) broker. The MQTT Transportation broker has been utilized as a platform to provide the Internet of Things services. Open-source software component is used for connecting sensors and actuators to the platform by the IoT end device via Wi-Fi channel. We created smart Environment scenario and designed IoT messages satisfying the scenario requirement.
