Design of Power Monitoring System Based on Internet of Things (IoT) with Calibration Interface

In a power monitoring system, accuracy is subject to change. Therefor, a calibration interface on the system’s dashboard is required. This research aims to propose a design of a power monitoring system with a calibration interface based on Internet of Things technology. For the hardware, this research proposes the use of CT sensors, Arduino, and Raspberry Pi. Node-RED is utilized to process the data and to create the dashboard. The proposed design consists of two dashboard pages. The first page is the monitoring page, which displays the measurement of voltage, current, frequency, true power, apparent power, and power factor. The second page is the setting page, which allows the user to calibrate the measurement by adjusting the parameter value on the dashboard. The proposed power monitoring system in this research offers simplicity to maintain the system’s accuracy.
