Abstract

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