Abstract

This study analyzes the measurement accuracy of electrical parameters (voltage, current, and active power) using the PZEM-004T v3.0 sensor integrated with the NodeMCU ESP8266 microcontroller and Blynk Internet of Things (IoT) platform. Experimental testing was conducted at the Electrical Engineering Laboratory of Universitas Muhammadiyah Palembang by comparing the PZEM-004T v3.0 readings against a calibrated True-RMS Digital Clamp Meter across 7 variations of household electrical loads. Results show that the PZEM-004T v3.0 sensor achieves an average measurement accuracy of 97.18% (2.82% error) for AC voltage, 97.50% (2.50% error) for AC current, and 97.00% (3.00% error) for active power. System integration via Modbus-RTU UART proved stable in transmitting real-time data to the Blynk platform. With an overall average accuracy exceeding 97%, the PZEM-004T v3.0 sensor is proven to be feasible and reliable for smart energy monitoring systems (Smart kWh Meter). Keywords: PZEM-004T v3.0, NodeMCU ESP8266, Blynk, Measurement Accuracy, Smart kWh Meter.
