Development of an Electricity Loop Current Monitor System Based on MQTT Broker

The energy monitoring system is always a critical and popular issue for a long time, although many information systems have been built and deployed into schools, factories, schools, commercial organizations, and governments. For many years, most of them have closed systems based on their business considerations, so add-on sensor types or heterogeneous hardware and software integrations are the bottlenecks. The study is carried out to integrate the internet of thing (IoT) and message queue telemetry transport (MQTT) to design a mechanism and to implement a prototyping clouding platform as the proposed system to develop the AC collectors with electricity loop current sensors connected to the proposed controller with Ameba 8195 AM in the study. The AC collectors are deployed in labs and classrooms in the National Chi Nan University and classrooms in Xinhe Elementary School to validate the usability and feasibility of the proposed controllers and the prototyping web system. A distributed message-deliver is developed as a publisher based on MQTT Broker to implement a central message-collector as a subscriber to transmit all data into the proposed system. The analytical and visualized reports are created for users and administrators in the proposed system to offer useful and real-time information as feedback to be the proof of concept (PoC).
