Industrial Internet of Things (IIoT) Based Energy Monitoring System (EMS) Using MQTT Protocol and Node RED

Abstract

Issues addressed by an Energy Monitoring System (EMS) include inefficient energy use, waste of resources, and high operational costs caused by energy inefficiency. An EMS also addresses challenges related to a lack of visibility into energy consumption patterns, difficulty identifying areas for improvement, and the need to support environmental sustainability through reduced emissions and wiser energy use. 

By using a network that uses the MQTT protocol, it can also be easily accessed remotely. However, there is a problem that the sensor data obtained from the readings must comply with standard parameters that apply to all sensors. To solve this problem, the Modbus RTU and Modbus TCP protocols are the right choice. This study discusses the implementation of the Modbus RTU/TCP protocol in the Industrial IoT scope. The electrical energy monitoring system can be implemented in networks located far from the control or monitoring center.
