Abstract

The purpose of this research is to use low voltage power line as media to transfer the measurements result ofelectrical quantities. The Arduino is used to read the electric quantity from the PZEM004T sensor output andsend it to the receiving device for being displayed on the LCD through low voltage power line (PLC). Inorder to be able to communicate through the power lines, a signal modulation and demodulation device areused, namely FSK KQ330. The results of this study indicate that the deviation of reading from the PZEM004Tsensor is 0.34% for voltage, 0.43% for current, 0.82% for real power and 4.11% for the calculation of totalenergy in one hour (Wh). In addition, the sending of measurement data packets by transmitters through thepower line has been well received by the receiver with an average testing distance of ± 10 meters.
