In every aspect of human life, electronics play an important role. An electronic solution for remote meter reading and power supply control is a power line communication (PLC). The development of such a PLC-based system for the power distribution network may enable automatic electrical billing. Power lines that already exist and connect every home in a specific area are more advantageous because they don't need to be installed in order to build communication channels, making them quicker to establish. Less work is required, changes happen quickly, and the system is cost-effective. The frequency shift keying (FSK) modulation is used for data transmission across electric lines. Based on an FSK-KQ330, the power line communication system was created (carrier modulation and demodulation module). The system's main processor is an ESP32 microcontroller, while the modem module is PLC-KQ330. The system consists of an isolation circuit and a resonant circuit. Data signals can be sent via electrical lines using a master-slave arrangement. It is not just applicable to intelligent home systems but may also be used to remotely control intelligent switches and equipment. In this paper, the above-said process is totally automated, and communication is made possible entirely through the power line.
