IoT based Electrical Energy Consumption Monitoring System Prototype: Case study in G4 Building Universitas Negeri Malang

Energy monitoring system becomes an important subject to provide information of electricity usage for the users. Moreover, with rapid development in information technology, especially IoT, it is possible to establish better energy monitoring system by providing real-time consumption data. In this paper, IoT based Electrical Energy Consumption Monitoring System Prototype for G4 Building Universitas Negeri Malang is developed. Real-time measurement of the energy consumption utilizes current and voltage sensors for each wiring phase of the building electrical panel. For the IoT system, data is processed and displayed in Web-based system using Public Subscribe method. This prototype is implemented during work-hours and achieving 95.5% accuracy based on the electrical data of the G4 Building.
